Ok since you can't guarded what I mean here goes, how about the calls barely connect. How about it drops calls whe they do and you can barely hear the person on the line. Oh how about I have to delete the app just to add it 100 times to see if the calls will go through and even though most of the time before I go to use the app to make a call before I do it says Connecting at the the top. No it's not ny wifi or cell connection I've checked everything and it's not that I have giga power & 5G.

Over a month now, this app has been frustrating me. I can't access my contacts, and the contacts that I've called before keep saying invalid numbers 😳 I can only call 2 contacts now, of which their names were erased by slickcall. It's showing just numbers. This app used to be really good. But then it stopped. I'm tired of calls not connecting to bluetooth always. I've tried several times to call slickcall, but they wouldn't answer my calls. Once I finish this credit, I will delete this app.

They are not open. the company will only allow you to send topup to relatives once within 24hrs. they will block your account from sending it, yet encourage you to use your credit card to fill up your account. I still have £5 with them, and they refused to refund it. I will not encourage you to use this app.
