No correspondence

On the 15 March 2016 I took my hauwei p8 lite into vodacom Hazeldean branch because of a cracked screen. They booked it in for repairs and said it would take about 7working days for it to be repaired. From my experience with vodacom I expected an SMS saying the phone has been booked in etc. 7days came and went and not a single SMS. I let it go thinking maybe because of all the holidays there was a delay. On 31st march my husband went into the branch to enquire upon which they rep**** insurance approved the repair and they waiting for parts. On Monday again hubby went in and he got a surprising answer saying phone has been fixed and its R627, I nearly died! So we go from zero correspondence to a ridiculous amount. No quote sent to me to get my approval...ZERO!!! when I personally go enquire they say that its a new phone (that's probably supposed to make me feel better). So after insurance approves repair they decide it cant be fixed and give a new phone (now im really confused) I am utterly disappointed in this service and refuse to pay that ridiculous amount to get my phone back. I have been inconvenienced for 2weeks without a phone and now this!
