[Resolved]  Urban Company — Water filter native m2 model

I purchased on Flipkart site for a urban native m2 model, this is an iOT device, but every m2 model to connect with an mobile the mobile has have 4g handset therefore I'm having a 5g mobile handset, so it won't connect through with water filter system. Flipkart saying they only can replacement but if I replace for this same model same problem will happen. I want a full refund
