Worst billing team

Rain has the worst billing team ever I was double debited last month after doing an upgrade and it's been 2 weeks now I try to call them every time I call I have to explain the same thing not sure why don't they log calls and they keep saying they will call me back my query is still being looked at but no one is calling. I actually spent so much airtime trying to call them but they not assisting they have the worst consultants not helpful at all. RAIN I just want my money back please and you guys can fetch your router I will look for a better service provider
