Pathetic service

On the 9 September 2015, I noticed that R550.00 was removed from my account,thereafter I proceeded to the Capitec branch in phoenix plaza, I spoke to a consultant,Senzi Mbhele,she could not understand why that money was removed and was labelled under discription as interest, she could not have an explanation for me as this account was not an overdraft facility, she thereafter contacted her head office and they also were unable to provide me with feedback , however I was promised that I will be contacted in 48 hour's and provided feedback, however that was not the case, had to leave early from work on the 18-09-2015 to speak to the consultant and get feeback to my query logged 7 days ago,the surprising part was that when I viewed the statement on the 18-09-2015, the entire transaction that was viewed on the 09-09-2015 was delted however thank god that there was an incident number. Logged on the 09-09-2015 as I would have had no proof that the transaction even occured, the incident number that was logged was ***6, I do intend on closing my account. Please can you help me hello Peter.
