Unacceptable paying nearly R1000 for a phone I don't have...

<p>We have had a contract with Vodacom for about 6year's now. My Sony Xperia z5 that I've had for just under a year ( so it's supposed to still be under warranty ) has been acting up and on the 13Februarie017 I handed in the device for repairs. Today is the 25th of April 2017 and I still haven't received my phone. After having the device been sent back and forth between Vodacom outlet and Vodacom repairs we finally got through to someone who gave my husband the banking details to pay for the repairs which they didn't provide the first time they called with a quotation. Now we have paid for the repairs although we do pay about R200 insurance every month with the phone's payment.... The monthly payment has also gone up by nearly R150 a month for data that we didn't ask for and I'm not even sure that I receive the 1gb data for every month I get R200 airtime and of that I usually buy 1gb of data... What am I to do?</p>
