Phone not activated

I app**** for a new cellphone contact at telkom mobile centurion mall. They advised me that it will take a day for approval. Whereas other stores issue contract and phone immediately. They call after 2 days notifying contract is approved and should come in to collect. After collecting I receive a call from the store saying they have given me the wrong phone and I should come in to take the right phone. I advised them that was not my mistake I should not be the 1 going to them. They did bring the phone to me. Its now been 6 days since I received my phone and sim. The phone and sim is still not active. I called the store 4 times already and all they say is they will call me back and they will do the activation. I even called the call centre to try and activate the sim and phone. The guy at the call centre said that there was no other atempt or log to activate that sim number and IMEI number. Clearly the people at the store **** to me or dont know what they are doing.
