Refused Service

I went to the Fourways Mall MTN store to cancel a contract on behalf of my sister who is residing overseas. The consultant who was assigned to assist me conducted himself in a completely disrespectful and unprofessional manner. He refused to assist me with the matter before him and failed to provide helpful information. He proceeded to shout at me when I insisted on receiving information and service that was required.<br> The matter before him was as follows: I needed MTN to cancel my sister's contract as it had reached full term. Paul Zimba, the consultant, told me my sister had to physically be at the store for the contract to be cancelled, despite advising him that my sister resides in the USA and it would be impossible. I requested for a solution that would assist my sister, I even requested for contact information that would assist the process but he simply refused. Instead I was disrespected by this individual where he made condescending remarks in the process. I requested for the manager, which he also refused for me to speak to. I had to request his colleague to assist me in the matter. The service and treatment I received from MTN through the company's consultant was awful.
