MTN not worried about their customers

I am extremely mad and really unhappy with the service myself and my husband have been receiving from MTN . We have had our contract with them for some time now and now i am due for an upgrade however we have been struggling with this for over two weeks now. My husband has signed all the required documents at MTN Carnival Mall however they are still unable to provide me with my phone or a reason as to why i am not able to get the phone. My husband has gone in every single day after work. This is a bad customer experience and i feel that they do not even care about it as we are just another customer. We are at the point of canceling both our contracts and porting to another network as i am a RM at another telco and i know that the service will be better. MTN headoffice is apparently not able to assist either as advised by the agent at the store. Is this really the type of service you give your customers. The contract is for 081*******1922
