Can't get through on email and phone

My account has been over charged. I have been trying to get hold of someone for 3 days now. I have emailed and called numerous times with out success. I understand that you might be short staffed due to the virus but surely after 3 days someone would respond or the phone will get answered?

A few months ago I contacted the car salesman, where I purchased the vehicle. She gave me a number to get hold of you guys to query 2 policies that are being debited. However, I have not been able to get hold of anyone and I have no idea what these policies are for.
