RAIN

I changed the date to debit my card from the 25th to the 1st on the website under my rain and the changes were well accepted , on the 25 to 27 I kept getting sms that they will cancel the connection and on the 28th March they did cut the connection 5 minutes after they cut me off I paid R479 and I was reconnected immediately and then on the 1st April they take another R479.00 I called them 5th April to rectify this, They acknowledge the billing mistake and give ref Ticket *** from there they go silent - I called back gain today and repeat the same story and I'm getting another story that is not making sense , why was I billed twice ? I just want my 479.00
