Refund demand letter and evidence checklist — ready in 5 minutes.
The machine charged you $60 for 2 hours of parking when it should have been $20. You didn't notice until later.
The parking company says 'you used the machine, that's the charge.' You need a formal demand letter.
You have a receipt, but you need to prove the overcharge. You need a checklist of what to gather.
Your credit card may be able to help — but you need to know the right reason code.
