********** upgrades/contracts and misrepresentations

I received a phone call from an "MTN" sales agent end of Nov 2017 who I only now found out was actually a third party agent to MTN , Summer Mobile who **********ly upgraded my contract to a 24 month minutes contract without my knowledge and now due to this I cannot upgrade to get a new phone (mine was ****** in July 2017, so I did not even need a minutes contract) which I explicitly explained to the agent and she said I would be able to.

There was no paper works, no emails, only a **** representative from MTN who upgraded my contract on my behalf without my consent or knowledge and **** to me about everything.

I would like this "contract" cancelled immediately!

Nobody should be doing any business with Summer Mobile as they are ********** and actually ruining MTN's reputation.
