Thank you gift gone bad

I ordered and paid for flowers etc. and chose the specific date it was to be delivered. The person who should've received the gift was only available for a certain period at the chosen address. A few days passed and I had not heard anything from Netflorist. I had also sent proof of payment to the relevant email address. A called Netflorist and obtained another email address. Once again I did not receive any feedback and called again. The consultant then gave me another email address which I had sent the same email. The following day, the day before my person was no longer available and almost a week after the date the gift was supposed to be delivered I called again and this time another consultant assisted me. I resend proof of payment and they had to arranged alternative delivery. None of my emails were apparently received and I eventually gave them another email which emails ended up in my spam. The point being, even when making payment and using their reference, you will not receive your gift if they did not receive your proof of payment. Even thought you send your proof of payment a million times, you will not receive your gift until you fight with them.
