Unable to get through to call centre

For the past four months I am trying to contact a consultant on the 808 number as I was told by the local MTN store consultants that the only way to cancel my contract was to call 808. However every time I call it rings then goes through to the automated voice prompts and after a few minutes cuts off. This is no exaggeration but I call up to about 50 times on the days that I do try. I did get through on two occasions after about midnight and I was told that the section that deals with cancellations closes at 5pm and I should try the next day, needless to say I do and it rings and cuts off after a few minutes. I was also asked for my details and told that someone will call me, however I am still waiting. I was back at my local MTN store this weekend and I was told that the reason there is such a high volume of calls and calls get disconnected is because the 808 call centre now also manages another companies calls. My contract has expired in August 2014 and once this issue is sorted and I cancel,I will definitely choose another service provider and I will never take another contract or renewal with MTN again!<br>
