@Nashashuk , is this a new credit card addition to the account? You may want to try using incognito mode. When entering the address, leave the unit number field blank. No spaces in the postal code. See if these strategies work.
I checked all my info at least a dozen times, I can't get PM to process my payment :c
Did you talk to credit card customer service? Maybe there's a problem with credit card company.
Didn't talk to my credit card company because I used it previously with no problem with PM and just today with other companies.
I don't know wich one of these solutions did the tricks but I tried them and it works now! Thank you three for the fast answers
Had the same problem. Using Firefox browser. Leaving the apartment number blank was the solution for me. Must have tried a dozen times before finding this. Thanks a ton.
