Bad service finance of Ford Ranger through Wesbank

On 2 Nov my son (P.Bloem) and a friend (Mr Lindeque who was retrenched), went to Wesbank Three Rivers. My son wanted to buy the Ford Ranger from his friend, and the vehicle was financed by Wesbank. They started the application. I was handling the documentation for my son as he was working night shift. Lee-Roy sent email regarding documentation, we have sent all the documentation through asap and the bakkie went for the inspection on 13 Nov. I have sent the inspection immediately to Lee-Roy. After 1 week I had to phone Lee-Roy and find out what now? He then send the Terms & conditions which my son signed immediately and I have sent it back. They then send the icontract to sign. Liz at Wesbank Three Rivers phone my son to sign the original contract. I also phone her and she said that the money will be paid over that same day (26 Nov). I have phone Lee-Roy and he promised me that the the money will be transferred to redeem the loan from Lindeque. Yesterday (2015-12-07) Collection Solutions Pty (Leander Klein) phoned Lindeque and ask him for his payment!!! Lee-Roy never returned emails nor phone calls. Is the finance on my sons name or what? Why are they phoning Lindeque??
