UPGRADE NEVER CUPTURED - NO UPGRADE DONE

Cell C upgrade department phoned me for a new upgrade, (01.10.2015) I was very exited and asked for the following Epic 150 - R449.00 Per month, I will receive R150.00 airtime and the Samsung S6 Galaxy Flat 32GB.<br> Tiffany the lady who assisted me, said that I have an Top up contract and this they will have to migrate to an open line, I will still have a balance on my old contract of R385.00 and this will be devided into 3 months and then my First three months deduction will be (R128 R449 = R577). I agreed. She read me the terms and conditions, where I agreed, and Tiffany confirmed that my new contract is good and my phone will be delivered within the next two/three working days. She also recommended that I can also phone Cell C back after 48 hours, to put a control on my account so I don't exceed the R150 limit. Yesterday I phoned Cell C to find out where my phone is, just to be told that there is no record of my upgrade. I was very disappointed, and could not believe that this has happened. I have 3 contracts with Cell C and at this stage I don't know if I am comfortable to proceed with any of these contracts anymore. Cell C will have to compensate me for this treatment
