Pathetic Service

I had two Getbucks accounts. I was placed under debt review and the accounts were settled through my debt review company. Getbucks asked my debt review company to stop payments as the accounts were paid in full. I even have the correspondence, The accounts were settled in 2015 or 2016 already. Still it reflects on my credit report that I owe Getbucks money. After numerous calls to Getbucks my query still haven't been resolved. My account was handed over to Getbucks attorneys. I asked them to investigate as well and not even they could provide me with a answer. I have all my statements from my debt review process showing deductions for Getbucks so how come no one can solve the query and provide me with paid up letters? Should I make use of the Ombudsman to help in getting this query resolved????
