My question involves a consumer law issue in the State of: New York and maybe the headquarters of the credit card company.
I paid my credit card -- Juniper/Barclay's Bank -- with automatic payments from my bank. The credit card company says they did not receive the payment and they did not notify my of a problem for 7 weeks, then they charged late fees and increased interest and minimum payments.
I have proof from the bank that the check was mailed timely.
When a person signs an affidavit of service, that is only proof of mailing, yet any court accepts that as proof of delivery. Isn't proof of mailing sufficient for credit card payment?
I really doubt this payment was lost in the mail. I believe the credit card company lost it, either accidentally or intentionally so they could charge me fees. Can I sue them in small claims court in new york?
