HORRIBLE SERVICE FROM VODACOM

I am sorry that I have to even give this a star - on Sunday the 10th I upgraded online 10min. I then checked the specs of the device and decided to rather cancel, within one hour!!!!!!!and wait for the right device or go to a Store to upgrade, but to my surprise now more than 48hours later I am still waiting for them to cancel the contract, it is one excuse after the other and the courier has even contacted to deliver - OMW !!!! they are quick to upgrade but when you don't want the deal the are not at all interested to speed it along...they want your business but please do not dare to question them. Everyday i call they say 24--48 hours, but that has passed already!!!!!
