Pay With Zero Delay

(I returned a defective item with a well-known online store and receive an invoice for 0.00 Euros for the replacement. Considering this the end, I put it on the paid bill pile, until the “friendly reminder” reached me that they now want 0€ and a “reminder” fee of 15€. Cue my call with their support.)

Me: “I got a ‘reminder’ for a zero-Euro bill.”

Support: “Yes.”

Me: “Yes what? I’m now supposed to pay a delay fee for a bill that was ZERO EUROS!”

Support: “Yes, I have it here on my computer. You didn’t pay the original invoice so we had to send you a reminder and that entails a delay fee.”

Me: “Lady, how am I supposed to pay ZERO EUROS? It is absolutely impossible to transfer zero Euros.”

Support: “Well, now you can pay 15, can’t you?”
