Non delivery and total lack of interest

Sunday 20th December 2015, no Sunday Times was delivered although I am an annual subscriber. After phoning 3 times I was told the matter would be escalated and a newspaper would be delivered before 12.00 pm. An SMS was sent to me that the matter had been escalated. By 12.00 no newspaper had been delivered, I had to go out and buy one R20.00 and no credit was past. Today 27th December 2015, the same as last Sunday, telephone call made, promise that the matter would be escalated, the area manager would be notified, an SMS was received to this effect, and again nothing!. Since July 2015, many a time I don't receive the 'The Times' daily newspaper which is also paid up with the same subscription. The same story, a phone call, a promise etc, and nothing. 16kms away from home and at my work address The Times has always been delivered even on the days that I don't get it at home. It makes me to believe that the area manager just doesn't care. Various emails have been sent by me to various addresses in the newspaper, I have never received an acknowledgement or a reply. No service delivery, I am paying in advance for newspapers I am not receiving, and no credits passed.
