Mothers day Delivery FOUR DAYS LATE

I ordered a large and expensive bunch of flowers and chocolates to be delivered on Saturday (9th May) before Mother's Day. The delivery did not happen on Saturday as promised and I received a short email on Saturday night saying that they were committed to delivering on Mother's day and not to worry. Mother's Day came and went and no delivery and no explanation. Same thing on Monday 11th may. So I spent ages on the phone to the call centre who once again PROMISED to deliver the flowers that same day and to return my phone call and explain what had gone wrong. Once again NOTHING happened that day. Finally the flowers and chocolates were delivered on Tuesday afternoon. By then, Mothers Day and the 'special thought' was long gone. Have had no apology from netflorist. Terrible service.
