FRUSTRATED AT THE WORST SERVICE

I upgraded on the 6th of November and according to your website a confirmation call should be done by 48 hours! My calendar as I sit in front of the computer states that it is today the 13th of November!!!!!!! This is more than double the 48 hours. Every time that I make a follow up the same is answered "THERE IS A BACKLOG". When I have a backlog at work then I have to rush to do my work and get up to date. Several emails from Customer Care was sent to the relevant department and STILL NO CALL!!!!! Today again, i wanted to cancel the upgrade and upgrade to a better phone ON THE SAME PRICE AND AND BETTER DEAL, the answer as SORRY IT CANNOT BE CANCELED!!! WHY THE F NOT???????? I pay my monthly bill and I have been with Vodacom for more than 10 years, happy to pay every cent, but the experience that I have no makes me wonder!!!! AND BY THE WAY, I HAVE 3 CONTRACTS WITH VODACOM AND THIS IS THE FIRST TIME THAT I EXPERIENCE THE BAD SERVICE!

CAN SOMEONE THAT HELP ME WITH THIS WHOLE ****SHOW PLEASE.
