Erratic indications on messages

Even when a message is read, it reappears as unread later. I do not understand how it is Hapenning. No pattern.
Also, marking a message as spam does not work. The application crashes.

I wish it possible i won’t even give your app any star.

I want my money back, you should please take your number back, because I don’t get people text, it just a big waste for me. This is a big mess, my text are delivering to my friend but I can’t get their text. That a big rubbish and wasting of money... anyone who is about to use this app, just don’t waste your money, if your friends don’t have the app, and text you from the app, no way they can get your messages unless they call you that all. For anyone who is in the United state and buying purchasing +1 number. I so hate why I just wasted money for 3 month. If possible please refund my money back, I don’t need your number anymore, as I can’t get people text only their call and my text is going through.

I don’t receive text messages - support won’t respond

I wish I could give this app 0 stars...I bought 2 numbers...text messaging doesn’t work fully. I can send text but can not receive text. I reached out to onoff through every channel possible and did not get a response. I was trying to give them time to fix the problem before I gave a bad review...but here I am. I will be getting my money back for sure. DON’T DOWNLOAD THIS APP!
