Circle K

On 12/31/19 I went into the circle k store #1967 at about 5pm to get $10 in gas and $20 cash back. The employee advised that my transaction was declined. I was stunned and taken back at the time. So while still in the store I signed into my account from my phone to verify the funds. My account then showed the charge as a pending charge as if they took the $30 from my account. So I left the store without any services received. I then called my bank and they said it shows as a pending charge if it doesn't drop off and the funds aren't returned into my account within 48 hours to call back to make a dispute. Later that day the funds did return into my account. I thought that was then end of that when low and behold on January 30, 2020 I noticed a transaction on my account for a "Provisional Credit Reversal" that was a debit for the amount of $30. When I had never even filed a dispute to receive a provisional credit. So it took my bank about 2 weeks to figure out what this charge was. It didn't say to who or from where or why. Here I am now on 2/21/20 writing my complaint because my bank advised me today that the January 30th transaction was from the 12/31/19 $30 charge from circle k that they provided to my bank that it was an approved transaction. So now I'm out $30 for nothing that was ever received. And now I've been trying to contact the circle k corporate office for accounting and NOT ANYONE ANSWERS THE DARN PHONE. LACK OF CUSTOMER SERVICE AND LACK OF ACCOUNTABILITY. I REQUEST A FULL REFUND BACK TO MY ACCOUNT IMMEDIATELY.
