Beyond terrible service

On the 14th of October I placed an order through Mr Delivery, after about 30 minutes I was notified that the driver was outside, so I went out to find no one, I waited a further 10 minutes only to receive a phone call telling me the driver is outside which i told them he wasn't, I was told to wait and they would contact him, a further 10 minutes later I had heard nothing and called them back to find out what was going on, 5 minutes later the driver pulls up with a huge attitude and told me he was in the other Fordyce road which I told him there was no other Fordyce road, he then stood there and argued with me and tried to give me my food which was already 20 minutes late and cold, when I refused to take it he got ****ed off and got back into the car to contact head office to tell them I wouldn't take it, this went on for another 20 minutes with the driver being told to get out of the car by head office and communicate with me, which he didn't do, he rather sat in the car and spoke to the person who was with him, a few minutes later he received a phone call from head office giving him permission to leave but instead of telling me what was happening he sped off down the road. I had to contact the branch to find out what was going on. Later I received a call from head office saying they were going to process my refund and it will be sent out to me asap, this took them a week to process, once I received the confirmation stating it would be between 2-5 working days I thought everything would be okay but no it wasn't 5 days later I still hadn't received my refund so I emailed to find out what was going on. All they did was sent the proof that it had been sent which of course did not help me. I then emailed back and waited to get basically the same response. We are not on 7 days that I have no received my money and now my emails are even being ignored. I called head office to try and sort it out and was informed that the matter had been escalated 2 days before that and that my emails were being received and opened but not responded too, I am still waiting and no body is willing to help me.
