Renewal of Contact

I was informed by the call centre that I needed to upgrade my account in July and that I should go to the office for assistance. I went to Greenstone mall twice ,First I was told that they could not pick up my account as the 2 phones I had was under someone Else. The assistant then called someone on the phone for assistance to correct it.I was told to come back which I did ,Going back Saturday a new agent tried assisting me and could also not pick anything up,but the call centre could after 2 hours he told me that I should wait for approval after 48 hours and come back.I asked for the Supervisor but I was told she is busy and they could not tell me how long she will be as I was willing to wait.I just wanted to upgrade the phones and continue with a the contact and pay what ever extras I had to pay.
