Poor Customer service with rude consultant

I cancelled my service plan with them, and I was promised to be refunded back the money if I didn't use their services with the Liquid capital Service plan, it took Westbank 4 months to resolve my enquiry, now I must get my money back into my account, liquid capital refunded Westbank my money, there are saying they cannot refund me instead they will put that money into my vehicle account, but the said part is that I'm now in error of R1900 which is I don't have, I'm really dissatisfied and miserable with the service.
