This debt is not valid. I 've sent two letters to Transworld Systems regarding the XXXX XXXX. The XXXX XXXX commited fraud with false advertising. I returned the product which was received XXXX XXXX, 2015 at their company. I lost {$140.00} to the XXXX XXXX and they have their product back in full working order with no damage. Transworld needs to stop harassing me over this non-valid debt.
