Telkom worst service ever experienced in my life

Worst Service! Actually no service! Telkom sold a ADSL line deal to us, we cancelled our previous service (big mistake!) for this "better deal" We waited 6 weeks, phoning the Sales call centre everyday, and everyday they ensured us that everything is in order and our service will be activated within 24-48 hours. Sometimes they promised to call us back in two hours (never did). We eventually gave up and cancelled the order and now we have to wait 5-21 days for our line to be released. Basically holding our line hostage after failing to deliver a service. I do not understand how Telkom can do this without being held acountable. It is so unfair towards paying consumers. They cause so much damage and unplanned expenses, but they just stonewall you. After asking several times to speak to a manager one sarcastic lady told me that the manager just quit, right after telling me there are no managers available, and after that that they are all in a meeting. After telling her I am not getting off the line untill someone tells me what the problem is, she told me I can hold the whole day if I like, but she will only be able to give me a ref. Number ( for the 20 th time) for the complaint that they apparently put through to "backoffice" or "itdepartment".
