XXXX erroneously submitted my account to a collections company ( Southwest Credit Systems ) about an amount that I did not owe ( i.e., unreturned equipment and early termination fee for home security ). I returned the equipment and did n't terminate my home security contract as I transferred service due to moving. This is all well documented. Southwest Credit Systems called me several times, including at work and I asked them to stop. In addition, I told them that I was disputing the charges. They indicated that they were looking into it. Well, they are still persisting in trying to collect for an amount that I do not owe via letter after I told them that this was in error.
