Samsung - Poor Customer Service

I purchased 2 Samsung air-conditioning units on the 12th of November 2015 from Game Bellair which included installation vouchers. On the 13th, I scheduled the installation with Samsung whose first available installation date was 19th November. Samsung sent a subcontractor Independent Aircontioning Service (IAS) to install. They did an extremely poor job and even broke one of the units. Ever since then, I have been trying to get Samsung to resolve this issue without success. I escalated to a Ryan Clay at Samsung as well as the Samsung customer support centre. I was issued with a claim number - ***. On the 27th of December, Samsung sent through another of the accredited installers to assess the installation. His report to Samsung was that both units need to be replaced, the one was badly damaged and new units installed. The living room unit was to be swopped out with a larger unit 18000 BTU which was agreed to by Samsung (Ryan Clay). Ryan Clay has subsequently left Samsung and I am having endless hassles to get Samsung to resolve this issue. It will be three months shortly and I have still not been able to make use of these air conditioners that I purchased in Nov 2015
