Payment

Money is being deducted from my bank account were as my rain account is up-to date. I made a call on 29 May and they acknowledged that it was a mistake on their side. I asked if the they can refund the amount back into my account, they said it will take 7 to 10 working days which was ok. Now my rain account is credited with R1214 and telling me that it was rolled over for the next months which I wont pay for but I need the money to pay my rent. Yesterday another R641 was deducted again and I do not understand what it is for? Now am behind with my rental because of this and I am not getting any help. Please assist me I need my money back.
