Wesbank - my experience was terrible

I financed my vehicle over 7 years. I finally paid it off. In order to get my ownership docs Wesbank now want me to send proof of payment....and it must be in pdf, I must also after 7 years send the. Proof of my bank account from where I paid my last installment.....what a load of ****...they were happy to take my payments for so long..... I now have a buyer but....can't sell as Wesbank refuse to send my natis docs.... been on hold to them now for 12 minutes. Useless..
