Wesbank Pathetic service!!!

I Bought a new vehicle that is financed by wesbank. Wesbank went and linked my new vehicle account to my father's internet banking. Why this was done I do not know as he had absolutely nothing to do with the buying of the vehicle...... I phoned wesbank call centre 8 times now. Every time they tell me that the call has been escalated and the problem would be resolved with 24 hours. It has now been 8x 24 hours and still nothing. I have also emailed wesbank twice to try and sort this out. However not a single response. I went to FNB 3 times to try and get this sorted, but the branch manager keeps on telling me that they did not link the account and wesbank needs to sort it out. How can they in the first place give someone else access to my account, and now not be able to get it sorted out???? Totally useless and pathetic
