Extremely Bad Service

This is the second day I have tried contacting ABSA Car Insurance to no avail. I have tried 4 times yesterday and 5 times today. I have been sending emails and to-date I have not received a call or any assistance. My debit order was taken off with an amount of R235.50 extra, which I was not aware of.. I understand this might be a busy period for ABSA but surely you can contact your clients. This is extremely frustrating and I feel like consulting another bank. 2 days contacting you holding on for not less than 15 minutes at a time is totally unacceptable.
