Fed up can't cancel contract

Hi<br> <br> I took a CAT phone out on contract at Vodacom Hemingways East London so I had the phone for 2 weeks then it started giving trouble. <br> 1. Phone takes long to switch on <br> 2.Contacts disappear <br> 3.Phone freezes <br> 4.Phone downloads what it wants <br> 5.Cant unlock the phone when you lock it and don't use it for a while <br> 6.Cant swipe the phone to answer incoming calls <br> 7. Screen reaction doesn't work. <br> <br> So Hemingways said I should take the phone to Vincent to send it to Jhb so we did. This is the 4th time I send it in its still not fixed Vodacom doesn't want to help me to cancel my contract latest is I have to buy the phone to cancel the contract. I pay every month for the phone and used it for two weeks phone is under three months. Every time I send it in they even use my data. WHAT AM I TO DO. Was there today they don't care laugh me out and don't care. Now they want to send it to CAT self and I have to pay for a phone yet again I don't use!!!<br>
