Fix Call Issues While Live and Offline

I have been using the Chamet app, and for the last two to three days I have not been receiving random calls at all. Previously I was getting random calls normally, but suddenly they stopped. My Chamet account email is r.bhutta1***@gmail.com and my Chamet ID is 182883***. I contacted Chamet customer support and explained that I am not getting random calls even when I live. Their response was that I would not receive random calls unless I live, but the problem is that even while I live I still do not receive random calls. This means their explanation does not match what is actually happening in my account. I request that my account be checked in detail and that the random call feature be fully restored. I would like to receive as many random calls as possible while I'm live, and I also want to receive as many random calls as possible even when I'm off‑screen. I kindly ask you to resolve this issue as soon as possible.
