Angry customer

So a few days ago i recieved a call from an agent at MFC advising me that my account is in arrears , I ask the lady to please explain to me the reason for this as i have paid my account upfront for 4 months in July 2022 was told that the vehicle premium would increase during that period but was never advised by how much. The lady confirms an sms was sent to me in September i advise the lady i never recieved the sms i want a statement and proof of what she telling me, furthermore she mentions that an amount of R200 some odd is of a long time ago and the difference is due to the increase.

Now in all fairness i have not recieved proof of the sms Nor have i recieved the the statement I asked for in addition to that i asked for a form to change banking details which until this hour is still not recieved

As furious as I am right now am sure next thing I will get an sms saying I have Missed my Vehicle Premium after I specifically asked for a form for the third party to sign for change of banking details

It goes without saying that I will take this matter further as there is no practice whatsoever of TCF in this situation the agent failed in her duty yet im being handed over
