Incorrect Fibre Package Upgrade

In March 2021 I have requested Telkom to upgrade my Fibre line from the old 10/5Mbps (25/5Mbps) line to the new 25/25Mbps for R449, instead they have upgraded me to the old 20/20Mbps (New 50/25Mbps) package for R699, I can see this on my invoice and my speed test. I have escalated this several times (+-30 calls from March to July) with the upgrade/Order department and nothing has been done to resolve my issue. Every time I call in with the reverence number, they escalate it to the so-called managers and that is where it stops. This has been ongoing for 4 Months now. How difficult can it be to resolve an issue and mistake made on your side? This is costing me R250 per month more than the package I have requested, and if I want to downgrade to the correct package I initially requested or cancel my Fibre line I have to pay fines.
