Incorrect Data loaded on Contract upgrade and no assistance forthcoming

I upgraded my data contract at MTN Clearwater on Thursday 05 October. I had a 3GB Contract and asked to be signed up for the 20GB/20GB contract on promotion (Page 2 of MTNs October Brochure) at R299 which they said they would do. The contract I signed and was emailed to me (as it wasn't printing at the time I was there), says it's a MTNChoice 10GB with 20GB Night Express. The data had not shown on my account, so I went into the store on Saturday 07 October to find out when it would appear. I was told it should reflect when my data gets renewed, which is the 17th of the month. I checked on my MyMTN App which shows my data as an Internet Bundle of 10GB and Night Express of 13GB. I contacted both the Clearwater branch and Customer "Care" regarding this discrepancy and the man who had initially signed me up on the contract told me that "someone" hadn't loaded the promotional bundle onto my account and forwarded it on to the "relevant" people, with reference number # ********** . Customer Services also got back to me and supp**** me with reference number # ********** . Still nothing has been done and no feedback given. I contacted Customer Care and the Clearwater Branch again on Wednesday 25 October. It is now Monday 30 October and still no response or rectification of my account. After being with MTN since 1996, I feel this is not the service that a customer of 21 years loyal patronage should receive and being pushed from person to person or flatly ignored, does not bode well for my continued use of MTNs services.
