Telkom LTE, worst idea I have ever had by far, kindly prove me wrong

By far the worst service I have ever experienced from any "service provider" ever. Upgraded LTE contract in June and was advised that if not sufficient data, it can be changed to a higher plan at a later stage (after 3 months). No problem, pay for additional data month to month which is already going over the monthly contract amount on its own. During this time enquire again, get advised that it is not how it works, recording listened to, advised that it is correct, I can do the merge to a higher option. Now, I do not want to end the contract, I actually want to give you more money every month, at a reasonable tariff. Now past the 3 months, try and do the merge/upgrade. No luck, get directed to a branch, query logged, query resolved, no way of upgrading. No natural person to speak to. I do understand that it is Covid and it is a struggle getting hold of anyone due to short in staff etc. Please understand that most of SA is currently working from home, which is almost impossible without data!!!! Telkom is more than welcome to contact me on ***, alternatively after more than 4 years, I will be cancelling my contract and moving to a service provider who actually provides a service. LTE Line in question, ***. I assume I will not be hearing from you
