Product: Credit card or prepaid card

This is the second time Ive been violated by Capital One in the past 2.5 years. I am praying that, as the first matter was resolved satisfactorily, I also hope this matter too can be rectified. I've been a loyal Capital One cardholder, on and off, for over 12 years. I was very surprised on the morning of XX/XX/XXXX to learn that one ( 1 ) of my active capital one credit card accounts were suddenly placed on restriction and are now in the process of being closed due to inactivity. After speaking to the customer service representative, and an escalations manager, ( XXXX in Tampa ) I was informed that because my account was closed on XXXX XXXX that attempting to have the account reopened was too far beyond the redemptive period. This was disheartening to hear considering the email I just received said the account was restricted and would be closed on XX/XX/XXXX. Meaning it was not closed yet. To add injury to insult, her telling me the account was closed on XX/XX/XXXX was the first time I had ever even heard of this. I was never alerted to anything prior to me receiving an email on the morning of XX/XX/XXXX. The representative in Tampa asked for my mailing address in which I provided and said I should have received a letter stating my account was closing. To this date ( XX/XX/XXXX ) I have not received anything from Capital One except for the email I received on the morning of the XX/XX/XXXX. This was really a harsh stance coming from Capital One considering that, Ive never missed a payment on any of my Capital One accounts in over 10 years, and also that I was never warned that I would be in jeopardy of losing the account due to its inactivity. If I would have been made aware beforehand, I wouldve gladly utilized this account .Not only to prevent a forced closure from occurring, but to also protect my credit profile. I am really worried how my credit is going be affected by this, as my available credit is going to be reduced significantly. Maintaining my credit rating is of utmost importance to me as some of the treatments I received are financed. Because of this, any substantial drop in credit score can affect my ability to finance my treatments/and or cost me more in interest to maintain the same level of service Ive been receiving. Closing this card could potentially create a financial hardship for me. As I think back to the previous experience I had with Capital One, although it was resolved, this created a fear within me ( of them closing my accounts ) of adding authorized users back to my cards. And by me not utilizing this option, I feel this was a precursor to me not having the activity I needed to keep this account open. I am ok with Capital One meeting their business requirements, and making account adjustments when they are required, but in my case I was never alerted to ANYTHING. I bank with other financial institutions and have encountered situations like this before in the past, but never have I been treated so harshly and unfairly, especially without recourse. After being loyal to Capital One for so long, and being a responsible cardholder, I truly hope and pray they will make an exception regarding their inactivity policy, and reconsider their actions and reopen my account.
