Idirect is misleading client

I'm disappointed by the way you failed to act accordingly to the amended contract that we had agreement on 18th February 2020 where I was supposed to pay less Instalment from 1st March 2020 but even now I still don't know what happened to the agreement. I got a call from one of your representative Mbalizethu then I told her that I wasn't in an appropriate space to address my issue and I had never got a follow-up call from that day until now. So now I will have to pay another incorrect amount whereas the problem is on your side? If you guys don't wanna help me just tell me to take my money elsewhere... I have sent emails but you're not helping
