Arihant Books — delay and no information about my paid order.

I ordered my books worth 440 on june 16. Today it is july 2 but till i didn't receive any information about my oder. My order i'd is 45291. I paid for my order and still no information abt the delayed delivery time. I contacted their customer service through email and phone calls but no response (Very poor customer service). Better instead of cheating people better close ur online portal. I need action to be taken about my complaint. I need either book or my money asap and even my exams are nearing. I would never ever order anything from this site.
