When I called Hertz,
You need to conduct matters in writing.
Put the issues to Hertz head office including:
You hired a van for **** hours/days from their branch in ****;
You parked adjacent to their offices in a car park which also serves B&Q and ** and in which *** Hertz vehicles were similarly parked;
When you returned their vehicle you parked this in the same car park, completed their paperwork and left in your car;
*** days later you received a parking charge notice from TPS alleging that you breached the parking conditions in the car park and requiring payment of ***.
The breach was that you parked your personal vehicle in excess of the maximum period allowed of 3 hours.
You raised the issue with staff at the on-site office who were unable to resolve the clear conflict between ***'s claim upon a bona fide Hertz customer and Hertz's business which rents vehicles for periods of up to ** weeks. The only bright side in this issue is that you are glad that you did not hire a vehicle for an extended period because apparently TPS's charge of £100 applies per day.
You have 'appealed' to TPS stating that you were a customer of Hertz and had their implied permission to park you car. You have provided proof to this effect. You hope that this is the end of the matter with TPS, but in any event you feel compelled to write to Hertz.
There is no warning given by Hertz either during the booking or collection process that customers' own vehicles may only be left on site for a maximum of 3 hours. You do not know whether this is an oversight or the company are intentionally disguising this limiting condition which, if known to customers at the booking stage, would fundamentally undermine Hertz's operations at the site. But whatever the reason, you would hope that in their response Hertz would confirm that they have reviewed booking and parking arrangements for this site and made the necessary changes to ensure that, in as much as they apply, customers are fully aware of any restrictions and action which they should take should they be served with a parking charge notice in error.
Just some thoughts.
