Payment issue

I have an account with Vuma and was disconnected because of payment. So I decided to go pay. Then I went to 5 different retail stores to pay as I used to and was told it's offline. Then I went to Vuma website and I got a number to watsapp them. I told them I am struggling with paying at retail stores. Is the another way I can pay? They sent me a link to pay. I thought it's like DSTV where it takes you to your banking app and pay for the service. Now from the 19th to today I dont have internet connection as they say they can't pick up my payment. I contacted Webafrica who also say they waiting for Vuma to respond to their query. What kind of service provider are you serving if you can't resolve a simple payment allocation issue and fet me reconnect? Its either you get me reconnected or you come remove this thing and let us part ways.
