FED UP IS NOT THE WORD!!!!!!

I do not know what to do anymore or where i should complain anymore because you just don't get any action out of Vodacom so i have decided to stop paying my account if this is the only way to get action from them then this is how it will be! I cant pay for something you **** have support or service Vodacom just don't even know the meaning of customer service, they would rather just lie to you and tell you we will get back to you with in the next day well it is almost a month later again no answer from these useless service provider and that is how it has been going since November 2014! Tell me what is should do? You have advertised a phone for a price when i upgraded with the first billing up to now the price have changed from the advertised price of R179.00 to R299.00!!! Why do you keep on lying to your customers? How may other customers did you also cough with the same trick? How many other of your consumers is also complaining about the customer service? The WORLD should start to boycott VODACOM because you cant keep up with standards infact I cant thing of a more useless service provider although you don't even provide a service because you are just not capable of providing!
