Today November 2nd 2023 I attempted to purchase gas with my Conoco card and was told that the purchase was denied. When I arrived and called customer service, I was told that my account was closed. There was no notice of this closure. There is no reason for this closure. Living in snow country as a senior citizen the closure of my card creates difficulties. My account has never been late in payments and in fact, I have had a 0 payment due for my account for sometime. I don't drive much and pay of the total balance each time a purchase is made, In fact, often before the payment due date. The customer service representative said that a letter would arrive and was sent on the 13 of this s month--did he mean October? Because today is the second. To date, no letter was received. The representative said that the reason was based on too many credit cards: I have less than average and none of these have been late in payments. The only reason, as far as I can assess is discriminatory. And i believe that if a review of this company's closure of accounts is made.
