MAKRO- Poor customer service

Makro doesn’t care about its clients. I bought a bmx kiddies bicycle for my daughter in December for her birthday and since that day the bicycle hasn’t worked. Chains and bolts always constantly falling off every 2 days. Everything my husband got tired of constantly reconnecting this bicycle then beginning of April around 4th April I logged a return and since that day not a single update from makro on the status of fixing this bicycle. Any update or feedback I received was because I actively reached out to makro myself. It’s been a month and half now I have not received this bicycle. Now I don’t even trust their ability of fixing this bicycle. How can it take them from 04 April to today is 15 may just to fix a bicycle. I don’t even want that stupid bicycle anymore because my daughter complained about it from day one. I want all my money back that I spent on purchasing it because it’s never even worked and plus makro has really upset me with their poor service. I’ve run out of excuses on what to tell my daughter when she asks about her bicycle. Order number is OD*** - ***. Can I get my money back ASAP
