I had no problem cashing checks at a local merchant.Dollar General. One day a check went thru on their machine but never went to the bank.Several days later tried to cash another check, denied. Called Certegy and gave them the referrence #. They said check was bad. Not the denied check but the one that was okayed by their machine. Bank stated that they never recieved that transaction. Come to find out, Dollar General's machine made a mistake. It put only a partial acct number down. plus where the check number is suppose to go, it put the missing part of the acct number. It didnt put the check number down at all. So check didn't go to bank. Had to call collection agency with a phone number proveded by Certegy to get this fixed. Had to coordinate with bank and collection agency to have check paid. Cost me nothing but alot of my very expensive time. Anyways check was now paid for but it was at least another month not being able to cash checks!!! Finally the other day with Certegy's OK I was able to cash a check!!! Great!!! Short lived the very next day, today I was once again denied PERMISSION to cash a check by certegy! We need a list of all certigy's clientelle so as they can be boycotted!!!
