SCAM, FRAUD, DO NOT BUY this or related software from them. Nikhil, Shirley, Michael or whoever. They are promoting official WhatsApp API as Whatsappbusinessapi but its actually not official WhatsApp API. 1st they will pushed you to buy via crypto(there is no any other way to pay to them except bitcoin) then they promose you to deliver the script within 4 hours. You will be getting nothing except exuses. Apart of that, before payment, you will be getting replies immediatly. After payment, forgot to get replies.... Nikhil has promised me to delivered the script in 4 hours. I have paid him on 9th Dec, and after that till today, i haven't got the software lisence yet, nor script. I have submitted complaint to WhatsApp, Inc. also i will continue complaint to London police, cybercrime fraud, FBI & CBI to make sure that they guys cannot continue running this website or any other.
