In XXXX of 2014 I purchased a used vehicle from XXXX XXXX here in XXXX and was promised verbally that they would take care of the issues I brought to their attention before I signed for the vehicle, they never took care of the items which totaled in excess of XXXX. I stopped payment on my check in lieu of the repairs not being done and discussed this with the sales manager. I havent heard anything more of this until know and I asked for validation and informed them I disputed this and never was contacted again until now where the collection agency is making threats against me ( i.e., lawsuit, additional costs ) This is blatant misrepresentation under the FDCPA and needs to be stopped.
