Netflorist false advertising and regression on free gifts

False advertising!!!!! I acted on the Netflorist ad, which stated a free ferrero rocher gift valid for Fathers day orders delivered between 17 and 20 June 2021. I received the parcel this morning, however - no ferrero rocher. I called immediately, just to be told that it was only valid for deiveries between 18 and 20 June. It seems the previous banner had been changed, but I made 100% and double sure that I comp**** with the terms and conditions in order to qualify for the free gift. Don't bait people with promises you can't deliver on. This is NOT on NETFLORIST!!!!
