I was contacted about a debt on XXXX/XXXX/XXXX that I questioned the legitamacy of. The debt collector claimed I owed over {$500.00} for medical bills dating back to XXXX. I sent a certified letter asking for verification. 

On XXXX XXXX, I received a letter stating that the verified debt was {$19.00}. 

I received another call today, XXXX/XXXX/XXXX again claiming that I owe over {$500.00}. I was told they would have to verify the debt again.
