Customer service - Proof of insurance issues

I financed my vehicle via Wesbank. I get asked via SMS to verify my insurance. I sent an email to the address with the required documentation proving that the vehicle is covered. Now I get bugged daily via cellphone to ask for the same. And then the threat that they will activate their own insurance on the vehicle. I started to move away from Wesbank due to this and want to warn other people to do the same.

I get it that they want to confirm insurance yearly, but then they can provide an online platform where the customer can do this. And stop harassing your paying customers with these additional demands !!!!
