bad service

I phoned Netflorist place an order for my girlfriend on Monday 30th of November 2015, the lady that was assisting me told me that I must submit the proof of payment via email I told her that I will send it from the internet banking transaction since I added their account as beneficiary and she said it's okay, two day late when I'm querying the order the lady who assisted me told me that I was supposed to send the proof of payment vial my personal email address since the internet banking proof of payment is taking forever of which that's is not true I resented the proof of payment into my email while I was busy with her on the line .Now this cause a tension in or relationship .
