Vodacom

On the 3rd of July I took out a contract with Vodacom. I experienced problems with the phone in the 1st 3 days and took the phone back. They sent it away for obs and 4 weeks later I'm still without a phone. I wanted to cancel my contract but the people at the Vodacom Chatz branch said they can't help me with cancellation(this is within the 14 days I'm allowed to cancel my contract) I phoned customer care for cancellation after I went to the branch and they told me I had to pay R6000 in order to cancel the contract(once again this was within the 14 days I was allowed to cancel my contract without extra fees) Today I phoned customer care and they told me the consultants were supposed to assist me at the branch. I spoke to a lovely lady at customer care I think her name is Lungile(couldn't hear clearly) just hope my issue gets resolved ASAP. Vodacom seriously sucks. I'm disappointed. I refuse to pay for a phone I haven't even used!!!
