Tenth Mega Sports Store confirms zero quality checks and poor service

So I drove 150km to this place to purchase a training javelin for my daughter who is close to provincial meet. Purchased on the 15th Feb 2024. On the Monday 18th Feb when I took her to practice we noticed a deformity obviously factory fault. While warming up the javelin bent on first through at this weakened area. I contacted them immediately reporting the problem. For an entire week I was given the run around, calling no answer on 4 different numbers. Then requested to send pictures via whatsapp no response after. Then got another number to call when person answers he will call back and never does so on Sunday 25 Feb I drove back to the shop. I explained my disappointment to the employee present that day that I had to drive again because of poor service. Only to be confronted by 3 things. First the employee refused to contact his manager and stated if I don't want to talk to him there is my javelin and there is the door leave. Secondly he refused to contact manager and made me call him obviously the guy will not pick up his phone as he does not know the number. Lastly I was informed that there is no return/replacements they are sorry to hear. Now today 26 Feb the manager messaged me and basically stated we have zero quality control and sell substandard products to the public because we have poor service and do not care to replace. I will use this info and communicate on all the school athletics and sports channels and social media describing their work and sales ethics
