Empisal sewing machine complaint

I purchased an Empisal sewing machine 120A in October 2021. It's now December and I have used it twice. The tension is completely out, and nothing helps. I have wasted reams of expensive cotton trying to get it right according to the manual to no avail. I tried contacting the store (Game Gateway Umhlanga) it was purchased from but they don't answer the call. I tried emailing Empisal SA, and was told that address is only for in-house e-mails. I am a pensioner and will now have to spend money on going to get this machine sorted out. Shame on Empisal! That a sewing machine should be manufactured so shoddily that it loses tension after two uses! My Singer never did that. Really, I am disgusted with Empisal. My advice to anyone looking to buy a machine would be stay away from Empisal. Read other reviews as well and you will see why. Totally unhappy customer.
