NO FEEDBACK ON QUERY

I have a personal loan with Woolworths Financial Services. I have been struggling since May 2015 for them to correct my payments. I have made a payment towards my one loan, but they awarded it to the wrong loan. I have been calling them on numerous occasions as well as written an e-mail, but to no avail. I am still struggling with this issue. I have now payments that are not possible, no matter how you look at it. I so wish they will come to the party and give some positive feedback! Each time I have to wait until the new account and then it is a struggle all over again because it has still not been sorted.
