Bad service an nobody taking ownership

I have a 4M line with uncapped Internet access. The line has recently become so bad that it is impossible to use, especially at night or on weekends.<br> <br> o I have logged a call in September 2014 and up till now has not been resolved and still is open.<br> Ref numbers 18atk240914.<br> The technical staff in the exchange have been very helpful and have done what they can but there is nothing more they can do<br> o I have spoken to Service Desk several times<br> o Every time I try and log a call with the service desk they say that there already is a call and cannot log another.<br> o If I try the SMS option it says that a call is already logged.<br> o I have tried escalating to [Email Removed] more tah 6 times. Nobody has contacted me yet.<br> o I have gone into the shop and they took down my details and promised a response. Nothing.<br> o Recently Telkom has send me and SMS and email offering a 10M line with DSTV explorer.<br> o If you can't provide a 4M line how will you be able to provide a 10M line.<br> o An now there is a price increase as well.<br> <br> I dont know where to from here
