WesBank Bad service

WesBank is financing my vehicle, and I have requested them to intervene between myself and the dealership because the dealership sold me a vehicle with duplicates vin numbers, they said they will investigate till to this day they don’t send the response from the dealer, I have reached out to Braiden Govender for feedback via email, he is not responding. I tried to reach him via phone call they said he is in a meeting, and the receptionist said he got the response from the dealer but she is not allowed to forward except Braiden, WesBank is failing me because every month they do receive their full instalment, they don’t care about service as long they’re making money, I think the best to consider other banks that will assist its customers
