Clueless MTN consultants, run around for an upgrade

I upgraded telephonically on Friday 2 July but see today that none of my account details have been updated. Called 135 for assistance, they made me call sales, sales made me call retentions saying they never heard of such a package, retentions turns out to be customer service. So as a consumer whose money MTN needs, I must be expected to take down all the details of the department I called, the consultany details, the plan details, double check if they actually do their job then be pushed around at my expense from department to department?
