Frustrating process for a refund

I discontinued a service on 7 January 2015 and yet it was only disconnected on 15 January 2015 after endless calls. The service was paid for in advance up to 31 October 2015. I have been trying to get the monies refunded and each call center consultant comes up with new conditions for processing. I have talked to Tebogo, Cleovette, Pamela, Xolani, Earl, Waheed, Charlene and today I was told it will take at least forty (40) days. This is unacceptable and obstructionist. I requested the contact details of the Finance Department and was either terminated on the line or given some fax number. Lying is the order of the day.
