Contract Upgraded telephonically additional charge

On the 3 march I tried Vodacom website to upgrade my contract but to o success, I then called the upgrade department who then could not help due to system issues. I received a call back late that afternoon from call agent who then proceeded with upgrading my contract telephonically. After some time transaction as complete and I received the phone 2 days later.<br> <br> I now got billed R150.00 for an admin fee, this morning I have tried calling Vodacom only to be transferred from pillar to post and after much frustration and venting my anger the agent dropped the phone.<br> <br> I was told that it is a different department that contacted me hence the charge. What a load of nonsense, this is the 1st I am hearing of it, I am now R150 out of pocket and highly irritated due to Vodacom BAD SERVICE!!!!
