WORST CUSTOMER SERVICE

On the 13th Nov. I put a complaint regarding the service and response on queries of Vodacom .. I got a message back a consultant will contact me but as we speak on the 1st Dec. no 1 phoned or collect the device that was cancelled the 31st of July .. its the next payment date and still I get charge for a device which I don't use AT ALL and no refund is made either. I am unemployed and want to cancel my 3G contract and later my cell phone contract the problem is that on my cv and all my communications for employed I have my current Vodacom email and cell number on. .. I was told according to Vodacom there is no problem with our signal in our area but as I told the gentleman that was here and also the phone call I received its only Vodacom in the surrounding area that has an issue no MWEB,TELKOM,CELL C nor MTN have this connection problem .. on Sunday 29 Nov. my friend had to go to work to urgent things on internet after we struggled an hour to get logged in on internet but according to the people that said they know we do not have a problem and I raised this every time with people I spoke to regarding this but NO1 can tell me what could be the problem its easy pull up their shoulders
