Wrong Account .Wrong people

On the 22 of January 2019 I visited cell c mall of Africa to get my gone fixed.I was advised by Busi that it can be fixed and she helped me with a quotation. I was given a number to call and deposit a excess fee of R200 to pay so it can be fixed. The insurance will pay the rest.They sent me details saying I must deposit the amount to that account. Then later on I got the message saying I deposited to wrong account so I must be advised that I must go to nedbank and reverse the money. The question is why did they give me the wrong account?.so now I must phone their head office to reverse the money as if it's my fault. Nedbank cannot reverse of as it belongs to Cell C.This is delaying me from getting what I have paid for.So unprofessional
