Food Panda — worst service provider

I had ordered on foodpanda and restaurant was 4 km away from my home the order was confirmed later on delivery boy calls me and tells that location is beyond 2 km so i have to cancel the order. My query is if the distance was too far for delivery boy then why foodpanda confirmed my order.? And why deducted amount will be refunded after 4-5 working days? This happened thrice with me in short foodpanda is giving very very worst service since last 2-3 months
