Vodocom bad service and goods

Hi there , I bought my phone in February 2015 from Vodacom in Johannesburg which is a Sony Ericson m2<br> aqua , the phone has been giving me problems straight out of the box up until now and I have to wait for weeks to receive my phone only to return it back to the store with same problem and no solution .<br> Vodacom has been taking me for a ride and I would like to have my money back if Vodacom cant fix the phone that they sold me in the first place.<br> This is my references for when I took my phone to Vodacom <br> The phones i.m.e.i number is : *** <br> <br> 1st Job No : ***8<br> 2nd Job No : ***7<br> 3rd Job No : ***0<br> 4th Job No :***5<br> <br> If you cant give my money back ,then give me a phone with the same value but not a Sony Ericson .<br> I do think that its pathetic to take the same phone back for repairs for exactly the same problem four times and getting no results.
