Yotpo Email Marketing & SMS

I had hoped to use this app for long time as it has great potential.
The first and only marketing text i sent almost 2 weeks ago was sent for some reason double(2 separate texts, one in the format we created, the 2nd was not in the format we created but same wording just not same lines etc) . so that is not good, since all the customers (2300 of them) got first text from us twice( doesnt look good)... Also they charged me double because their system sent it twice.
1. that is absolutely not my fault. I sent only one text (I clicked send one time for one marketing text campaign)
2. they should have credit my account immediately as this
3. They should correct this.is obviously their app mistake or glich.
4. they received all screen shots as they requested from me
5. I contacted them in the last 10days atleast 6 times about this issue that needs correction
6. They promised to give me an answer by the past Monday(today is Wed)
I am very disappointed.
I have deposited $500 with intention to use their services for the long run.
Now I have to fight with them to get my money back for the second text their system sent and the credit in my sms account, back to my bank account.

Update:

The owner Mike contacted me and corrected the double charge and claimed that usually it doesn't take 2 weeks to fix a problem. I will continue working with them as it is a good decent app as long as it does not have more double charge on our account. And I appreciate that Mike contacted me and fixed right away as it should... I will raise the star from one to 4.

Lord m'a beaucoup aidé a activer mon compte et ça a été très rapide merci.
Je recommande vraiment cette appli

Very good application and the customer service is of an exemplary reactivity! I highly recommend smsbump

Awesome customer service that responded within seconds! The app is super easy to set up and they provide a full easy-to-understand guide. I would definitely recommend it. It is a game-changer for online business

really good for abandoned checkout campaign but not for SMS marketing. invested 130 USD for the campaign and 0 return..

Excellent customer service. Had some issues setting up but the customer chat bar on the side is very helpful and paired me up with someone very fast. Issues were instantly resolved.

Liking it so far.. it has great features. They charge about 0.02-0.1 per SMS and the chat help is fast and effective. I'm in :)

I had asked question regarding the set up of app as I am first time user. Alex was very quick and helpful! Thank you.
