NetFlorist poor customer service

I ordered a gift for a friend’s bday (Cape Town). On receiving the receipt of payment, I realised that one of the items was duplicated and emailed them straight away. I then phoned and was told that I cannot cancel the duplication (cake) as it was a user error but they will deliver both. When my friend received her gift, there was only one cake. We phoned and they said that the 2nd cake would be delivered the following day. The next day I received an email notification to say that she has received and signed for delivery, which was not the case. Sent 2 follow-up emails and nobody responded. Really bad customer service. Will not be using them again.
