OP, you made the right decision by filing a claim with your bank.
Let Yoogi deal with the USPS & file a claim.. This could take time..
(probably you would have been very close to your deadline)
You don't know if Yoogi's is going to refund you promptly or wait until
they file & collect the money.. IYKWIM.
And out of curiousity, would be interested as to how long Yoogi's takes
to respond to you now that you have received this letter & e-mailed to Yoogi's
If they refund you promptly, then you can cancel your chargeback)
YC haven't replied to my email yet.. Anyway if they refunded the money before the bank does i can cancel my claim ...
