Not even a 1 star rating describes this terrible company

Worst service EVER!!! Placed my order for burglar bars in December and paid a 75% deposit. They were supposed to install on the 6th January 25 but only after me sending a message did they inform me it wasn't goint to happen. We agreed to the 20th January 25 and again more excuses for them to not arrive. I explained that I cannot take off more days so they agreed to install my burglar bars on Saturday 25th January. I received a message requesting my address and was expecting them to arrive at 10:00. However, they did not. I sent numerous messages and tried calling. The phone is off and nobody read my messages. On Monday the 27th Jan 25 I started to threaten with opening a case of theft. Only then did I get a response. They are rude and basically told me I am welcome to collect the burglar bars, but the invoice was for manufacturing, delivery and installation. How am I supposed to fit these huge things in my little car when I was expecting the company to do so! I was told that I don't have a case because the burglar bars are made and it is not theft and I should read the bottom of their invoice. Disgusting attitude and service! I just want my burglar bars installed without this. They have also refused to give me a refund because the bars are already made, of which I must just believe them without any evidence.
