Failure to update

After been harrassed on numerous occassions to pay my woolworths account and personal loan, I made an agreement and paid both accounts and received paid up letters from easton berry, this happened last year. To date my account is showing in arrears on itc and I still receive sms' from easton berry requesting payment. I have called in, emailed, sent my paid up letters back to easton berry and the four credit bureaus but my account still reflects arrears, I am so frustrated, easton berry you collected the money, you should have updated my itc by december 2014 already
