GL Attorney's Incompatance

Groenewald Lubbe Inc attorneys seem to not be able to read or check and verify numbers. For a year they have been harassing a company's number, to collect a FNB credit card debt from an individual. My company has no credit facilities, nor an account with FNB, yet despite six requests for my company's number to be deleted from their system, they persist. If this is the quality, they provide, no wonder they are not able to collect a debt.
