Discontinuation of my service

I am very disappointed with Rain, they currently discontinued my services even after paying them on the 21st of May, I've been loading airtime over and over trying to contact them so they can sort out this mess. You hold on forever and whe I finally got through line cut off and the lady didn't even bother to call me back after asking her so nice. Even their network gives me issues, so I'm a very unhappy client and I've been using them for quite a while with no joy. Yet they are too quick to increase their subscription fee. Please sort out this ASAP, this is an inconvenience since we are depending on them to even assist the kids for researches...I need an urgent response..call me on ***. Innocentia Mahlatse
