It was a nightmare for me while purchasing the AP 650 - a problem with the payment gateway wherein money debited from my account, but didn't get credited to Bajaao. Through the whole process reversal process which took 12 days in total, however, Jay from the product specialist team was of great help!About the delivery - it was done within two days. However, for a product such as the AP 650 digital piano (which comes unassembled in a box) installation should be provided at a fee, just so that one doesn't get it wrong and damage the equipment.
