FISGlobal.com / Certegy review: Check cashing!

I was at my local Publix Supermarket on 5/4/20 19:18 S1010 R151 3141 CO417 my cashier was Saveon A. which I wrote a check for groceries of $61.94 + a $20 request for cash back. I had been in earlier in the week and wrote another check due to my debit cards being hacked by Cash App! I do not nor could anyone @ Publix or Certegy give me any reason for the refusal of service. During this time in the economy of the world this company has dropped the ball in refusing a 2nd purchase at my local supermarket regardless of a proper balance in the required bank to be able to purchase from Publix, & upon more research, Kroger has the same check non-service in this time of need! the Certegy representative that I was in contact with was initially telling me that I was not within the guidelines of requiring check approval, but could not offer me any explanation of why I was otherwise refused. An intermittent connection on Certegys' phone recorded line made it additionally annoying not being able to understand ANY help or her offer for additional non-help! Your company's parameters OR guidelines are only to protect the company and NOT the guest's expectation of service! Certegy DROPPED-THE-BALL & I know that you probably don't care with all the jumping through the hoops to get to THIS very aggravating point...
