Have held a credit account since 2010. Made my payments and have paid account balances off. Have had a $1500 credit limit for many years and never have had an issue as to where my limit was decreased for an reason. Went into the local store on 12/26/23 to exchange a TV I purchased for my daughter, at which my account was verified and was told that I still had approximately $1,090 +/- spending limit available. Went back to same store tonight - 1/1/24, to purchase a Robot vacuum for my wife. Logged into account before going up to counter to purchase vacuum to find out that my spending limit has been decreased to $550 without any previous warning or notification. Contacted Citi Cards, spoke with 3 different people, to be told that, for one, a letter has been sent to me stating the reason(s) for a limit decrease, and two, they cannot verify or discuss those reasons. I told the representative that this has never happened before in the past 13 years I have held this account. The representative then tells me that the credit company / department has the right to review the account holder's credit information at any time, and that they can close or decrease the spending limit on an account at any time. IF my account is in good standing and has never been "reviewed" in the past, why now?!? This has definitely left a sour taste with me towards Best Buy, and I think it is poor communication / business practices that will drive long-time customers like myself away!
