NEED HELP AND ANSWERS

Claiming I owe them money. Handed me over to NIMBLE but neither Happy Pay or NIMBLE can provide details of when the account was opened, at which store the purchase was made, what was purchased and the date of purchase. Trying to get help and answers but nothing forthcoming. NIMBLE keep referring me to Happy Pay. Both want a selfie of me with my ID and address to continue with the “investigation”.
