Product: Debt collection

This is a copy of the letter I sent XXXX XXXX XXXX They still sent me to collections wth Synter Resource which I disputed. 
-- -- -- -- -- -- -- On XX/XX/XXXX, XXXX XXXX, my crew picked up a truck in order to try to finish a job as they were taking the next 9 consecutive days off for holidays. They picked up the truck that morning, but were never informed that your branch was closing early until later in the day, roughly XXXX, when one of your associates called my team lead, XXXX. By this time, the crew already had a half loaded truck in XXXX XXXX and had no way to get the truck unloaded and back by XXXX. ( Normal closing time XXXX ) Me and my team were forced to find a place to park the vehicle. As we are not equipped to store box trucks, which is the biggest reason why I rent them from you instead of own, we parked the truck in front of XXXX house. This is where the theft of the catalytic converter occurred. 

When XXXX was finally able to return the truck, Tuesday, XX/XX/XXXX, she informed the office that I would be getting in contact with you, and not to charge my card anything additional until weve had a chance to discuss this issue. According to todays bank statement, that request was ignored, and my card was charged for additional days that the truck was unused and in our possession. 

Here are the problems I have. In the 15 years that I have been renting trucks from XXXX, I have never been put in this position, and had we been informed that the office was closing early, we would have never picked up the truck. As we had not been informed of the early closure, we were forced into a position that we are not equipped to deal with. This caused additional days of possession and damage to the truck. 

I request that XXXX absorb the cost of the catalytic converter loss as this was due to the branch negligence of not properly informing us of the early closure. XXXX needs to take responsibility for this issue. 

If this requests is met, I will continue to happily do business with XXXX. Otherwise, I suggest that XXXX take legal action in a court of law where a judge can make a determination of responsibility. 

Finally, it came to our attention that you had another truck with a catalytic converter loss at the same time. This appears to be a significant and ongoing problem with XXXX trucks and I suggest that XXXX take additional measures to protect their fleet vehicles from these thefts by installing catalytic converter cages or similar mitigation steps. 
-- -- -- -- -- -- -- -- -- -- -- -- After receiving a letter from Synter Resource, I sent the following dispute, which to this day goes ignored, and they continue harrassing me to collect on an invalid debt -- -- -- -- -- -- -- -- -- -- -- -- RE : Collection notice XXXX Dear Synter Resource Group, I find it excessively distasteful, but not surprising, that XXXX has chosen to ignore my repeated email explanations as to why this is not a valid debt, and has retained your firm to try to collect. 
I am formally writing you to let you know as well that this debt is not valid. That if XXXX feels that they are owed anything from me, they have my contact information as well as my attorneys. I have invited them to take this matter to court. Obviously they know that would not result in the outcome they are hoping for. 
I am further requesting that you cease and desist from further attempting to collect on this invalid debt. 
I am sending a copy of this letter, along with your collection notice to my attorney, XXXX XXXX. I will also be saving copies in my file in the event that I have to escalate a complaint against your firm for continuing collection efforts against an invalid debt. 
Thank you XXXX XXXX XXXX
