For the past XXXX years, we have been receiving calls from Harris and Harris, a debt collection agency out of XXXX attempting to collect a debt that is not ours. The person they are looking for is clearly not at our address and has not lived at this address for almost XXXX years ( they were a tenant in a property we own ). I have called the company and explained the issue and that the person they are looking for is not at this address, however, the calls continue ( approximately XXXX per week ).
