Enough is enough

I've been disconnected again, the money that they say I owe is increasing as they reconnect n disconnect for no reason, I'm up to date with my payments, I ve sent proof of payments and asked to speak to superiors and they promised to sort out the matter up until now. I was so happy to see the article where there CEO apologies about over billing they do to client, thinking that everything will be sorted but it was just a dweng.
