Why send your Medical Guardian letter certified
USPS Certified Mail gives you a mailing receipt and a tracking number, and the Postal Service records when the letter is delivered. That record is what you point to if the company says it never got your notice.
Some contracts require certified mail. Others only ask for written notice, and certified mail is still the safest way to send it. Some contracts count notice from the day the letter arrives and others from the postmark date. The USPS record shows both.
Regular mail leaves you with nothing to show. A letter can sit in a mailroom, get misrouted or get thrown away, and you have no way to prove when, or whether, it arrived.
When we mail a letter for you, it goes USPS Certified within one business day of your order, and we email you the tracking number. You can follow it on the USPS site until it's delivered. The price is $29, paid when you order.
If Medical Guardian keeps charging you after you cancel
Check the dates first. A charge that covers your notice period or the last billing cycle may be allowed by your contract. A charge for a period after your cancellation date usually isn't.
- Contact the company in writing. Say when you cancelled and how, and ask them to refund every charge after your cancellation date. Include your proof.
- If they don't fix it, dispute the charge with your bank or card issuer. Give the cancellation date and send the proof: a copy of your letter and the USPS delivery record, or the confirmation number from your call.
- If charges keep coming, ask your bank whether it can block future payments to that company.
- File a complaint with your state attorney general's consumer protection office. It creates a record, and some companies respond faster once one is filed.
Banks and card issuers set deadlines for disputes, usually counted from the statement date. Don't wait for several months of charges to pile up before you act.
