We (two people at the same address using a car) presumably received a PCN from APCOA for accidentally not paying a Stansted parking charge in time. However, the address on the V5C was wrong back then (now updated) so we never received the PCN in post. We have now received a SMS message from PayDRP talking about an overdue parking charge, which cites APCOA and correctly names our car's reg plate, so presume it is not spam.
However, the SMS did not go to the registered keeper but to the other person, so not sure how to handle this. Had the keeper received the SMS, we would have used one of the templates to send a complaint to APCOA to drop the PCN and refrain from further contact, but not sure this is the way to proceed since we may accidentally reveal more than necessary.
While the SMS does not mention names, it is not clear how they got this particular number, and not the keeper's number.
How should we proceed in this case?
Thanks in advance!
