Bad service

Since May 2014 I have been trying to sort out my problem on one of my contracts. I have been given wrong info from Vodacom retentions regarding the upgrade. I was told that I could transfer airtime and data that I will get on the contract to another number. On that basis, I upgraded the contract. I found out that it cannot be done and Vodacom ignores my complaints. I even posted on Facebook and then got a reply but no action was taken to correct this. None of my requests or demands gets any attention and I get the feeling that I am deliberately ignored!!! Ref S3-8UL2O-OADKQ
