Absolutlely useless - couldn't be more disappointed

I placed an order for a chest of drawers from Pine Solutions having read excellent reviews of them and their product. I couldn't be more upset or disappointed with the service I received. I had booked my delivery in for 8th of October and was told I would receive a call telling me during which time slot my order would be delivered. I never received a call so I called the day before to check myself. The person on the phone told me they hadn't yet had their delivery schedule but that she would call me back. This was at 4pm. By 8pm I hadn't heard from her so I called back - still haven't had the schedule but I will definitely call by 9pm. No call. The next morning I called up as soon as the office opened and was told my order would be delivered between 1-3pm. Unfortunately I had to re-arrange delivery as at such short notice I had to work. I was told I had to pay £15 which was not a problem. The delivery was re-booked for Monday 13th. Same issue - no phone call telling my when my order would arrive despite being told I would be called on the Friday before. I took the day off work and was finally told after once again calling myself that the order would be delivered between 1.30 and 3.30. At exactly 3.30, a knock on the door 'I'm sorry we forgot to load the van'. Yes, really. I called Pine Solutions to cancel my order as I had now wasted enough time on this company. I asked for a full refund including the extra £15 delivery - assured not a problem and that it would take 3-5 days. That was a week ago and I still haven't received my refund. I called today and the person on the phone ONCE AGAIN promised to call me back. 5 hours later no call so I called again. The next person had no idea what I was talking about so the process starts again. I am on hold for 5 minutes before she gets through to finance to find out my refund is indeed being processed including the £15 delivery so I asked for email conformation. Email does arrive but the refund amount is missing the £15 delivery charge. Absolute joke. The poor staff on the phone tried to be nice which is the only good thing I can say.
