Zendesk

I am running a couple of stores with shopify and bigcommerce. I have installed Zendesk on my shopify stores including Jaipur Hair & Instalength. But their customer support sucks and i personally do not recommend. They didn't treat customers like customers when it comes to proper support we require being in India.
So instead of Zendesk, I strongly recommend Freshdesk or Freshchat. I have lost whatever i have paid them in front for annual plan. They didn't resolve the concern i have asked them to do instead they are like all the payments are non refundable.
Please do not waste your time with them.
