SHODDY unprofessional service.

I had a subscription in Gauteng which offered good service. I have now moved to the Cape & Independent Newspapers convinced me to continue the service. However there have been numerous problems with non-delivery of the already paid for subscription. After numerous emails & phone calls, no one can tell me what the problem is. I merely get told that I will receive a credit & they will contact the sub-contractor. What is the point of paying for something that does not get delivered !!!
