AVAF payment relief ****

In 2018 I bought a vehicle through my mother under AVAF as the interest was high for me, in July 2020 I was able to change it to my name, due to COVID-19 in September I app**** for payment relief, it was never granted however my payment duration was increased, I’ve been sent from pillar to post trying to get answers, each time getting worse answers than the last. There seems to be 0 willingness to help me or resolve the reasons behind why my term of payment and interest were increased without me receiving the app**** for relief. I feel ****med and as though they trying to sweep it under the carpet, I was told that it’s just a few cents difference and I shouldn’t complain, I’m highly frustrated as I was on the line for well over an hour
