Shockingly poor service

I must say I am very disappointed by the service received from Telkom and all its staff.

At the end of March/ Beginning of April I dropped my phone off for repairs at Telkom Menlyn Mall Branch and to date I have not received any feedback. I went to follow up last week and was told that the process does not take longer than 2 weeks(this is way after two weeks by the way) and that the phone was taken to an external repair center that could not be followed up with ?

This is now following a request to cancel all my services with Telkom on the 23rd of March which still has not been processed as well?

Is this the service that is being received by all it's customers ? Or is this kind of attitude and service reserved for just a specific few ?

Why has there been no feedback ?
