No feedback on LTE Migration

Earlier this month, Telkom Mobile released a new 50GB LTE contract for R699 p/m. Since my data requirements are larger than my current 10Gb+10Gb contract provides, it made sense for me to upgrade. After being told by in store and online sales people that I can definitely upgrade (for a minor fee) I attempted to do so. Long story short, I was ******ed around for 3 days before finally the phone side of Telkom assisted me and promised feedback in 48 - 72 hours. That was 2 weeks ago and still nobody knows what's going on despite countless phone calls and online follow ups (Reference ***3). I honestly despise dealing with Telkom, I'm always treated as though my business doesn't matter.
