Lack of support. Query resolution rate is 0%. Response turn-arround time 8 days or more

My Motor plan expires December 2023. I want to apply for extended warrant with my financial institution (MFC). All I'm getting from MFC is that, someone will call me back since 19 October 2023. I kept on following up and getting the same response. The call centre agent advised me to log a call on their website and I did 27/10/2023. Today 30/10/2022, I made a follow up with MFC call center. The agent told me MFC does not offer Extended warranty for the Mercedes-Benz. I was left with no option/s.....like that. MFC has failed to support me as a client, more than once in the 24months I have been with them. I curse the day I accepted finance from this institution and would never recommend them to anyone.
