10 days later with no solution

Thurs (25/2), my contract was upgraded online, the consultant contacted me immediately when I requested to upgrade online, after infor. was given, Vodacom (V) said my handset will be delivered within 24 hrs. Courier called me saying they have the incorrect add. supplying the correct add. I awaited delivery, when I tracked my delivery, it said my parcel was returned to V. When called V., they said for me to get my handset from a store I will have to cancel my contract, I then cancelled my contract and proceeded to V where I was told that the system was not updated, I then spent 3 hours with the call centre that told me I just had to wait (no expected time given).I called again & spent another few hours on the phone & then went back to the V shop where I was advised to go to Vodaworld, took off from work (2afternoons) & went to only be told that I had to call the call centre again cos the system was not updated. I sat again on the phone for about 4 hours, to no avail. I called about 20 times from Tuesday to now and still no help received, ppl. promised to call back, no one did. Contract was awarded in 5 mins, to cancel it's over 1 week later and not resolved. Can anyone HELP?
