Provantage partners of MTN(unprofessional and *****s)

I received a call in September from a lady claiming to work work for MTN.She said that they would like to upgrade my data and minutes FOR FREE.I asked this ******* and ********* about 3 times ,only if it's FREE, she can go ahead. She said ,YES SIR THIS DOES NOT AFFECT YOUR PAYMENT OR CONTRACT.October my MTN debit could not go off of R610 becuase they are now wanting me to pay R800, this after I was told nothing would change on my contract. I went to the MTN store who directed me to call Provantage.I tried calling Provantage several times if not more than 20 times to get hold of a consultant,but to no avail.Receptionist gave me a email address of their so called manager at Provantage.I email a lady by the name of Lee Ann Van Wyk, absolutely useless as the lair who upgraded my contract with out my permission.Lee ann promised that she was going to escalate my matter and that I will receive a call from MTN...I am still waiting for a call after 3 emails and 3 weeks ago.

I have been contracted with MTN since 2016 and have never missed a payment ,but thanks to Provantage and their ********** staff, I have been disconnected and cannot make any calls.I will not pay more than what I signed up for.

I lost business and was even stranded with connectivity having to ask assistance from people to assist me with making calls.
