Poor after sale’s service

My interior designer order all the electrical supplies for my new build, for total in excess of 50k. Unfortunately a USB plug and 6 Le Grand switches failed in the first month. My builder PDK to the issue up with Live Copper, and it’s been 2 months with no joy. The USB fitting has been removed and sent to live Copper. To date we have not received a replacement. In addition three is a hole where the USB plug fits, that is a safety hazard. 1 of the light switches is not working and 5 others have a crackling sound, which the electrician has confirmed is a problem with the switch. In addition I had to buy another replacement switch from another company as live copper had defaulted on their after sales service. These products are less than 2 months old. It’s not worth dealing with a company like live copper, and receiving poor after sales service. It’s unfortunate that my electrician, interior designer and builder seemed to be unaware of the poor service. My advice stick with a company that has a proven track record of after sales service. It costs time and money to escalate this issue further, to ensure the electrical items are exchanged or repaired.
