Muhelos Dean Hall fails repair

I bought a 3 in 1 travel system form Muhelos who was at the Dischem Baby expo at Grand West, Cape Town in August 2019 for babys arrival in 2020 . I tried to contact Dean Hall about a repair for the prams wheel. He responded and said he would contact the supplier. Dean Hall was kind and seemed helpful but then stopped replying to me. I have send them messages from their website and to his phone. I spend a good amount on the travel system and feel robbed. Dischem is my go to shop for baby products and trusted that this company was legit because it was at the expo. It was a waste of money because I need to buy a new travel system instead of just doing a repair.
