Upgraded a BF deal to a DATA only contract without my consent.

My last post takes preference. I thought i was finally settled with MTN as i had Annie call me from retentions and we went through all my lines and did upgrades accordingly, she was supposed to call me back that friday to confirm an upgrade but didnt call, no harm done, however, i get a call from summer mobile and they say i can upgrade so just out of curiosty i said ok tell me what you can do, and he went through my lines and i realised that one of my BLACK FRIDAY deals that i had running for the past 6 years was for some ODD reason changed to a DATA only deal, which means that my 500- 650mins and 50gb a month is gone, i called in now and the lady after 20mins says that she spoke to her manager and i that she will transfer me to the ***** department, next thing, call cuts, i call back and try to find the frauid department but to no avail, i then called retentions again and finally after 15mins someone answered and didnt say a word for 5mins before cutting the call.

All i want is my liens to be in order, revert the upgrade that was done without my consent, as its very silly to change a black friday deal to a normal data deal, please this is so stupid and now its just causing me frustration and irritation.
