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

Love this app! Makes it so easy to send texts to our customers without having to commit to a monthly subscription. The only thing I wish is that there was a code we could post that would like customers sign up for this program like many other texting programs have.

The chat support is very quick and provides prompt response.... Ppl should try this.. Good Work.. SMSBUMP.. Kudos to the team

Customer support was awesome, answered all my questions and resolved my issue on the spot. Very patient and kind during process!

Marnie helped fixed a couple issues I was having and it was very much appreciated! Give Marnie a raise!!!

Customer service is on point. I had to chat with two different agents because the first agent stopped responding, but Quin, the second agent, was on the ball and got me what I needed quickly. Really its 4.5 stars

awesome customer services and quick of the mark when asked a question.quick response and detailed. thanks Aleksandar V
