Poor service, annoying request for proof of insurance

After I layed a complaint against wesbank about them requiring me to send proof of insurance, a person in the complaints department contacted me last week and offered to update my insurance details on the system and said it was sorted out. This week they called me again with a number that appears as spam on my phone, and I did not answer, after that they send me an sms stating they tried to call me and that I need to provide proof of insurance. They also send an email on the same subject. Funny about this is, that I let my insurance contact them with all the details when I bought the car and they seem to have my phone number and email address so why don't they use the number I provided for the insurance and get it them selves as motor finance corporation does. I tried calling their call center and the call center is also not user friendly pushed all the numeric buttons to get to insurance dept. and just got a dead line. Tried again and skipped all the numeric prompts and got a direct line, and got re-directed. The lady who spoke to me was not really friendly and I at one stage was wondering if she still was in the line, she just ignored me and said I must send the details. So people please don't finance with wesbank use mfc or iny other finance, this is the kind of problems you run into the bank is so far behind they don't seem to have proper systems and staff in place to keeo proper records and to provide a proper service
