Bad service and Ill mannered managers

Took my phone for repairs on the 04/05/2021 and I was told it’s going to take 4 weeks to be repaired today (01/06/2021) went to the store to get the phone. I was told the phone was not ready. The managers there Thulani and Salome said the store can’t be held accountable since it’s the 3rd party. When they called the repairs department too many stories were communicated with no solution and accountability. I am really disappointed with the service and in all honesty I’m sensing disrespect for a store in Sandton city I felt the managers are taking advantage that I’m black. For a manager to say the store can’t be held accountable didn’t make sense to me cause I bought the phone at Ackermans and I expect them to account to service delivery. This kind of service and management skill are totally unacceptable.
