Upgrade nightmare

It’s been a horrid 2 weeks trying to get assistance from Vodacom. I was sent an sms confirming that I am due for an upgrade, I’ve spent more two hours on the phone with probably 10 different agents, being bounced around from department to department. My contract was initially a business contract but was converted to personal when I changed jobs in March 2020 - some of the feedback received “you’re number is linked to the old system and we need to escalate a call”, “this number is still linked to business”, “when they converted your contract, financials weren’t loaded”, I even tried cancelling the contract and got told that the contract is linked to someone else (a guy named Sydney) - the greatest frustration is the fact that each of those agents have promised to call me back but none have! Like mentioned, I moved off a business plan to personal in March 2020 and have been paying at least R1199 per month for the last 13 months, and haven’t missed a single payment in that period. Really disappointed with the service!!!
