REVERSE MY UPGRADE

Last week Friday 07/06/2019 I was called from Cell Network an authorized MTN branded retail channel partner to upgrade my contract as my current one expired, The deal offered was the 20GB day time and 20GB night time package, for R199, I agreed as it was less than what I was currently paying for data, upon reflection I decided I should rather get an upgrade that includes a phone as my current one has seen better days, I called MTN within 30 minutes of upgrading, who said it can only be reversed from Cell Network, they then put me through and the lady said she will process the reversal, then I started getting messages that a usage limit has been requested on my account, then my payment details have been updated, then twice that I have exceeded my MTN credit limit of R1220 by 75%, Then that I have been credited with 4GB data, then my unused night data has expired, then 2.5GB free ..... After a few calls to CCISA and MTN, I eventually called MTN head office and the lady told me that the upgrade has been reversed and that I can upgrade to get a cell phone,(ref: ********** 46) then I told her the data is still on my phone, the data needs to be reversed, she told me I will be billed for the data and I told her I cannot get a new contract if I am going to be billed for 2 and they must reverse everything as I am still in the cool off period of 7 days, then she told me I would need to speak to MTN retentions which she transferred me to, after having to explain the whole process again they said the data and invoice reversal can only be don't from Cell Networks side (Ref: ********** 62) and that he will send them an email and they will contact me within 24 hours, which has not happened, there is no phone contact details for Cell Network, and MTN itself cannot communicate with them effectively which is terrible since they are an MTN Branded retail channel partner.

Please just help me cancel the whole thing, you don't even have to revert back to my old contract, just cancel, cancel cancel.... This whole process has been very dissatisfactory and leaves me and many other customers frustrated with MTN.
