January R100 Query still NOT resolved.

On 29/01/2018 2*R100 transactions came from my debit card at the Century Gate Depo, when a time out occurred between my debit card & my city card. At that time i was unaware that the R100 had been debited from my account as my in contact messages only reflect if more than R100. So I placed my debit card into the slot again & completed a second transaction. This was then successful. Upon checking my bank statement on 02/02/2018 i noticed 2*R100 transactions, This was reported to my city on various occassions via telephone. Each time i phoned i was assured that i would get a call or email and i received a new reference number every time. I have now phoned & returned emails on 6 different occassions during these past few months. I have even sent through a copy of my debit card as well as a bank statement & my city card to prove and for my city people to check. I received a call from Fiona in May 2018 she called to follow up on my query.. which to date is still not resolved. I would like my city to refund my R100, as i feel that it is unfair & putrid customer service that i have to keep phoning after you to give my money. Every time i called then the consultant took down incorrect email address, or my name was incorrect or this or that.. Like honestly it is 6 months later, if i had placed that R100 into an investment account, i am sure i would have received interest by now. Not Happy at all!!! Would like some proper feedback from a manager as to when i will receive my R100.
