Promise promise promise ...

My name is Mr Hendricks and I am trying to have my number activated on a contract that I took out on the 20/11/2015 without success. When I took outthe contract I was told that my number will be activated within 2 to 3 working days. I am still waiting for it to be activated, even after more than six visits to the store , with the consultant insisting my problem was solved. I am getting so frustrated now that I am considering to try to have this contract canceled because im missing calls and my alerts and notifications dnt come through. My number is registered with the bank and other institutions so it is a must to have my number active. If I cant have this thing sorted out then I will seek legal advice to cancel this contract because I need my number.
