Proof of Insurance Harassment (3rd Party)

Wesbank are an efficient, good financial service provider and I’ve always used them. However, recently they have started using a 3rd party (Direct Axis) to harass customers and demand proof of insurance (That’s already been provided) and threaten to slap you with an inflated insurance premium if you don’t. Problem is I’ve supp**** it twice to Wesbank and still get the demanding emails. This is really underhanded. A 3rd party should not be responsible for “checking” if I have insurance - this should be done directly by Wesbank and without harassment.
