Very bad and absolute poor service

On the 8th of this month i`ve wrote a report about the bad and poor service from Vodacom after i`ve upgraded my contract. Vodacom rep**** the next day and wrote that someone will contact me in due time about my problem. Now one week later and now about 3 weeks without my phone not a single person contacted me. So it seems to me that Vodacom`s due time may take up to 2 years before they will attend to my problem. In the meantime i must keep on paying my contract and Vodacom just wants to sit back and milk me for the 2 years. Now i want to cancel my cellphone contract with Vodacom because i feel that i deserve better treatment than that i`m receiving from Vodacom. Due to Vodacom`s poor services in the past i`ve stopped one contract with them and now it seems to me that Vodacom does not care about it`s clients. So now i want to close my other cellphone contract with them and if they prefer they can also stop my data contract with them. Vodacom is absolute useless if it comes to after sales service and i`m having a 1000 times better service from MTN. Can someone at Vodacom please contact me to close my cellphone contract with them, why must i keep on paying for such bad service?????
