Bad company

Unacceptable yesterday the 6th of November is Roman's Pizza birthday and so I wanted birthday special and I go online to order and it says its available and I place my order for 3 of the R25 special and it is sent to the restaurant to confirm the order and they call back and say its not available . I am very disappointed as it said available still available online and the store is giving me another story. I always did buy form this company but this was just unacceptable I'll take my business elsewhere this was very unacceptable
