Ackermans N1 City Bad Service

Ackermans N1 City Bad service: I took in my sons phone for repairs on 21/02/2019. I received no communication or update on progress of his phone. I called Ackerman's N1 City today and was advised that they system shows that the phone was sent to courier. The phone has been laying and not sent to be fixed. It is going on to Month 2 and all the person could say was sorry...Not on! Their attitude is so pathetic. I want the phone back fixed by end of this week or they need to replace the phone. Why do you have staff in the store that does not keep customers in the loop even with an update. Clearly your staff need proper training on how to deal with queries/escalations or in general customer service. Keeping a customer in the loop is better than not communicating.
