Zendesk

Do NOT use zendesk for website chat, sms and phone. The software interface is not user friendly and looks like it was designed 10 years ago and never updated. We spent multiple hours trying to get it setup as there was very little help/tutorials available.
Voip calls have significant lag when answering the call and overall call quality is very low.
You cannot send an sms to customers in any simple way.
There is no mobile app for answering calls so EVERY phone call must be answered at your desktop.
When I requested cancelling today they screenshot the contract saying I have to give them 30 days so will bill me for another month.
Ironically their website support is slow to respond.

We have changed over to Coax app. So much better for about the same cost.

Zendesk claims to offer the 'world's best' ticket management system, but it undeniably has the world's worst customer service, the slowest response times, and never solves any issues. It's really terrible!
Zendeskは「世界最高の」チケット管理システムを提供していると主張していますが、それには間違いなく世界最悪のカスタマーサービス、最も遅い返信速度、そして問題を解決することは決してありません。本当にひどいです！
Zendesk afirma ofrecer el 'mejor' sistema de gestión de tickets del mundo, pero indudablemente tiene el peor servicio al cliente del mundo, los tiempos de respuesta más lentos y nunca resuelve los problemas. ¡Es realmente terrible!
Zendesk behauptet, das 'beste' Ticket-Management-System der Welt anzubieten, aber es hat unbestreitbar den schlechtesten Kundenservice der Welt, die langsamsten Antwortzeiten und löst niemals Probleme. Es ist wirklich schrecklich!
Zendesk prétend offrir le 'meilleur' système de gestion des tickets au monde, mais il a indéniablement le pire service client du monde, les temps de réponse les plus lents, et ne résout jamais les problèmes. C'est vraiment terrible !

Tínhamos as informações disponibilizadas do contexto do pedido do cliente sem custo algum, que desapareceram a partir de uma atualização e quando solicitamos novamente ele é cobrado pelo Shopfy. É um absurdo isso. A zendesk deveria continuar a nos disponibilizar as informações básicas do pedido do cliente.

I installed it to find dead ends to onboarding, and a reluctant support culture that is evident. There's also a superiority complex, "we're the best!" when it is not. I deleted it after an afternoon of research and trying. Hope you have better luck than I did!

Zendesk claims to provide the "world's best" ticket management system, but it undeniably has the worst customer service in the world. How ironic is that!

DO NOT USE ZENDESK. HIGHLY RECOMMEND GORGIAS!!! The irony of running a customer service company and yet having the absolutely worst customer service in the business is not lost on me. We finally upgraded our zendesk level, after years of them begging. They set it up incorrectly, and then absolutely ghosted us when we asked for assistance in correcting their error. So essentially, we paid for MONTHS for a service we did not receive. They are an absolutely terrible company. Please, please save your money and use someone else for your customer service needs.

Zendesk should really re-evaluate talent they bring in for their app development. Their apps are clunky, not intuitive and super buggy. Their mobile app is a disaster (just read reviews on the Apple's App store) App used to work just fine. Then, for no reason, the Shopify integration just stopped working. The right pane of the support ticket (in Zendesk) used to display Shopify's order info. That's gone now. App is showing as installed on both ends (Shopify and Zendesk) yet nothing works. Attempts of deleting and re-installing proved fruitless. I am permanently deleting this piece of crap and will be looking for Zendesk replacement.

horrible

Richtig schlechter Support!! Kündigen ist kaum möglich und man erhält keine Antwort vom Support. Finger weg

I first installed the app 2 months ago and got a "Ooops something went wrong" error, I've contacted Zendesk support twice and to this day still never got a reply... Very dissapointing.
