Constant Messages and phone calls

I have been receiving calls and messages from this company saying my vehicle finance with absa is in arrears. My account with ABSA is in good standing, please check with ABSA VAF, and not send me any messages or call me again. I just called your office now over 8min holding the line for someone to answer and no one to pick up. Please don’t violate our rights as consumers. Deal with your client which is absa and I should not receive any messages nor phone calls from you further.
