Disappointed, angry and of course frustrated

On 07 April I was depositing cash in the ATM in Kolonnade mall, the machine reported that some notes were folded and would be returned but they were not returned and no slip was issued. I called the number on the ATM while I was still there and I was I was advised that it would be switched off. The machine was subsequently switched off while I was there. I reported the matter at the branch the following morning and later received Service request no. *** via SMS and that it would be finalised by 15 April. I never received any feedback. I made a number of follow-up and also went to Hamilton branch (which is closer to my workplace). To my surprise I was referred back to Montana as they said they cant help me. I went back to Montana and nothing had been done regarding the matter. I then lodged a complaint and later received an SMS confirming Service request no. *** with a due date of 21 May. On 19 May I received another SMS that it has been resolved and I would be contacted with the details. I still have not received any feedback. It is also surprising that no one called me during this whole period even after they say they have resolved the matter, Im still waiting.
