Standard bank home loan account

I have a homeloan account held by Standard bank. The account went into arrears because I was unemployed and was handed over to Strauss Daly for collection.<br> <br> Ever since I started working, I have tried making various payment arrangements on the account without any joy. I then decided to pay the account monthly with an amount over and above the bond amount. Strauss Daly have changed the contact person more than 3 times and every time I have to start the arrangement process over again - The person handling the account now is Silindile Mkhize, whom I have sent various emails to have the payment arrangement made but she doesn't get back to me
