Poor judgment from Dischem

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. Dischem is my go to shop for baby products and trusted that this company was legit because it was at the expo which we attended yearly with friends and now it was my turn. My turn to get my daughter the best but it is just the opposite . It was a waste of money because I need to buy a new travel system instead of just doing a repair. I would think that Dischem would have done their homework a little better when appointing business to sell under their name.
