Pathetic service delivery

We have upgraded and we're told we would have to wait 2 weeks for a new phone to arrive. How does a big company like telkom not have enough stock in their stores. We went to the westwood mall branch in Durban. This is pathetic customer service from a big company like this. If this is the case we rather move to a more reliable service provider like vodacom. This is pathetic and something needs to be done or they will have no customers left.
