Poor response to requests

Placed an order for 2 items on 17th January. The items were to be delivered to the same person at the same address but I was charged for 2 deliveries. <br> <br> I contacted the call centre and was assured that they would issue a new order and credit the one delivery amount. However, the reissued invoice did not reflect the credit. I contacted the call centre again, this time the consultant couldn't help. I asked that a manager contact me, 18 hours later nobody has yet contacted me. <br> <br> When I tracked the order this morning, the tracking report states that the one item is being delivered, while the other is still being prepared, this despite the fact that I requested that both items be delivered at the same time.<br> <br> This is my first experience with net florist, I wouldn't want to repeat it.
