unfair and poor customer service

So I called wesbank and gave notice to settle a vehicle with them 3 months ago , I called Friday after 3 months . they tell me call 3 rd November , I then called yesterday 3 rd Novemebr for an interest free settlement as I gave 3 months notice , they gave me a figure which firstly seems incorrect ! Secondly they tell me its valid for 3 days and not 7 !!!! Why was not informed when I gave notice 3 months ago and told now its valid for 3 days ?<br> How can i settle this in 3 days when I need the normal 7 days , this is unfair . the sad thing is I have 4 vehicles financed with Wesbank , and I am settling this to finance another vehicle with them . This is how loyal clients are treated ? It does not speak well of wesbank !!!! I want the correct settlement and the 7 days !
