Dear Sir, Please review your firm's policies on expiration of credit card payments. Your firm just required a change of credit card on 11/2018 when the actual credit card expires on 11/30/2018 as per Wells Fargo. Earlier today we JUST received replacement cards and have not activated it yet today. We're not sure what your firm's accounting department is up to but their information is not accurate and the card you had on hand was used today without any issues. Should you have further issues, please investigate prior to your notices. Thanks.
