this is unacceptable as i was still planning to pay the rest but now i don't know what to do.

My Name is silondile Dube, i made arrangements to pay an amount of R2700.00 as i was settling the other account. however the company kept taking an amount of R4700.00 a month, i have been dealing with a lady named Pinky Gidzana. she assured me that i will be refunded the Double debiting that happened on my account as i did not agree on this. i am a single mom, so i need my money i was promised my refund on Friday by Pinky, i have all the email sent to her, the whole day today she is quite. when i called i spoke to a man he said that he was transferring my call to Jeanette from Accounts, Jeanette did not pick up my call, i asked for a settlement letter for 1 settled account i did not get that, I asked for a statement for the rest of the accounts that i am paying i still did not get one. So i now don't know what to do my R1965.55 have been taken just like that without me agreeing to be over charged and me being block from reversing this extra payment as i have been doing for the pasted 3 months. it seems like the guys there don't know what they are doing as its just double debiting for settle. how do i settle the rest of my account with them when they can not be trusted with my banking details which i now have to go to the bank and change
