bad service

During desember I dropped my S5 and vodacom was suppose to send me a loan ph before or latest before 10 on the 23rd. However at 09h00 I made a call and no one to drop it. On the 03/01 they picked up and since then giving me the run around. Can per ph discussion 7-14 working days till it will be returned fix. Today spending 2 hrs speaking to them they dropped the ph as they have *********** people behind the desks. Ph call after ph call and still no matter resolved. To.top it all they updated my platinum contract without asking me permission. Who do vodacom think they are? <br>
