Scan worst network - Rain

Had an account with Rain, was on R250 plan for over a year and later upgraded to the R299 Sim only plan and at the first of every month would have to call them to restore my network (not coz of late payment, my due date was on the 25th of every month ) which will take them about 2-3 days and that will be after talking to most of their agents. Sad thing all their agents will always pun a different story, then on 1 February 00:28am I lost my network (as usual) tried reaching out to them the whole day and I wanted to find out why it happens every month coz every agent I've spoken with had promised to solve the issue and it was never sold. Later that day I asked them nicely to cancel my Sim which they did and I was happy. On the 25th of February I was billed R479 and I queried this I never got an explanation, April was billed another R479, again I queried and was told I was paying for the few hours of 1 February (before canceling) and it was supposed to be R69, funny thing the network was down I guess I was paying for the 28 minutes it worked which was fine and fair by me. I went back on Facebook to ask about my money they've been taking the only thing I got was "its sad to see you leave us but should you need to come back and need of any assistance , don't hesitate to contact us" I even asked but my issue hasn't been resolved never go any response till date
