Delivery

i placed an order for deliver 8 May 2015, for my mother for mothers day, and my mom had to leave work urgently so obviously she cannot get the deliver, i phoned Netflorist to ask them if i can change the address and they could not assist me, if i had to change the delivery address they can only deliver on Monday, which is no use to me as it is mothers day on Sunday and i got no money to buy her something else... I then asked for the courier services name or number and was informed that they don't have that so i cant phone them. the hamper is of no use now. i mean i do understand that it is not their fault that my mom had to leave early but they not even trying to assist me. so the hamper is of no use...
