Vodacom - nobody cares. Customers must pay . Plea

Vodacom doesn't care about their customers. Don't renew your contract with them. They treat you like a ***hole when you phone to complain about the bad service your receiving. I, renewed my contract in June and I've had nothing but bad service. The new Samsung device that I took has been sent for repairs 4 times. When I stopped paying my contract, due to the bad service I received my, they locked my phone line. When you phone Vodacom head office and send a email to them nobody will get back to you. The account's department sends you a bill for airtime and data that you didn't use or even receive! !?. Who pays for a service that the didn't receive? ?!. The same department that locked your phone number then demands payment for their ''NONE SERVICE DELIVERY POLICY''. When you phone them to enquire about the billing nobody can answer you and when you want to speak to a manager they are not available or don't speak to customers! !?. Vodacom doesn't give a flying***** how they treat their customers. '' NO CARE @ VODACARE'' should be your new company slogan. I, will not be paying for a faulty device and service that I didn't receive.!! I've been a customer for 20 year's! !!
