Sold us a contract with no phone in stock.

My grandmother took out a contract for a new cellphone and it has been more than 5 months now and she still has not received her phone. The manager said that Shinaaz was not allowed to sell her the contract in the first place if there was no phone she is 77 years of age and still waiting for her new cellphone. Telkom is in complete breach of contract and should give my grandmother her phone and repay her for all the months that she did not have a phone. Please help us. This is completely unacceptable and any young person would have done everything in their power to get their new phone. She is old and she cannot stand in the long q all the time.
