Poor Service from Macro and Trojan

I purchased an Elite Spinning bike from macro October 2018 Trojan. After only four months it began making noises. I contacted Trojan who told me a Technician would come out to me to look at the bike but it would take weeks. I have had no feedback from this Technician. I contacted the Floor Manager of Macro, Montague Gardens, who told me that their Technician would look at the bike within 24 hours. That was two weeks ago. I contacted macro online support and despite receiving several smses within minutes from Evolution (their Technicial Support), stating that Technician would contact me within 24 hours, I still have not had a phone call from a Technician. It has now been three weeks since my initial contact with Trojan and 2 weeks since my contact with Management. Not only has Trojan proven to have a poor quality product, they offer no after service. Macro has also proven to have poor quality follow-up, after-service as well as no support. I will no longer support them.
