I just want to vent a little bit because I can’t stop thinking about my huge mistake I made at work. I feel so awful and disappointed in myself.

A customer called over the phone and wanted to pay a certain Amount on their purchase (we offer payment plans where i work) and I accidently overcharged a customer today $750 instead of $150. Our system at work automatically puts in the amount that is due at check out and you have to manually change the amount before you process the card if the customer is making a certain payment amount.

The customer only wanted to pay $150 and I totally forgot to change the $750 to $150. Anyways I noticed right after I hung up with the customer and got my manager to void the transaction immediately. I called the customer back and let them know my mistake and they started yelling at me because it showed the amount of $750 was “pending” in their account. I gave the phone to my manager and she was explaining how she voided the payment and nothing went though but the customer kept saying how now she won’t be able to use that money in her account until next week when the transaction would clear. (She originally had $1800 in her account).

She yelled at my manager for a good half hour and at the end I heard her tell my manager “thanks for calling me back even if you aren’t the one who made the mistake and should be fired”.

This was was my first huge mistake at my work since I’ve been working at this place for 4 months. I feel awful and I can’t believe I did that. My manager kept saying that mistakes happen and not to let it bother me because I owned my mistake and it was truly a mistake. She also kept saying not to let that ladies comment get to me because companies have managers to deal with things like that.

I know it was a mistake but I feel awful and it makes me not want to go into work next week. I just feel down tonight after that and can’t stop thinking about what I did.
