Standard Bank Poor Customer Service

I made an ATM cash deposit at Standard Bank Brackenhurst on Thursday morning 24 May 2018 and the ATM accepted the cash but experienced a technical error at the ATM and it gave a slip to take into the branch. I took the slip immediately into the branch and they phoned a contact centre and confirmed that the ATM had a problem. They gave me a reference no. and promised to email me the proof of deposit by the next day. I left my email address and cellphone no. with the consultant but received no feedback to date. I phoned their contact centre this morning Monday 28 May 2018 and was put through to the branch but no-one answered and the call to the branch and the call was terminated. I tried phoning their contact centre again and told them what had happened and the consultant said that she will try to phone the Brackenhurst branch before putting the call through to me. I held on for 8 minutes before the call got terminated again. I am totally disgusted at the lack of customer service from Standard Bank. This is not the way a customer should be treated.
