Worst customer service, EVER!!!!

Selby Branch - On 10 June 2020 I took my empisal overlocker to the Selby branch for a service, as the machine was breaking one of the threads. A week I after that I phoned to check if the machine was ready or not. The lady who answered the phone was rude and said they will contact me, I don't have to phone. The machine is not ready yet. Today, 24 June 2020 I asked my husband to check if the machine is ready and pick it up. He phoned me, the machine is not working and there are no needles or thread on the machine. I sent it there with needles and thread as. Status from "Home of Living brands" machine is not repairable, needle clamp broken. There was NOTHING wrong with the needle clamp. I actually worked with the machine and only sent it to be serviced. Then I got it back the machine was not even opened, and my needles are gone. If you cannot do the work why take in the machines to be repaired / serviced. The same machine was taken there in 2013 for a service, it was never used, until now. So this also means that the machine was never worked on in 2013. I will never use them again, and will discourage anyone wanting to go there not to.
