Caller claimed to be from Lazada it and there had been an attempt to set up an account using my number and to purchase an apple iphone via Amazon wallet. Requested that i authorise them to cancel the order - and to do so needed to have my Amazon OTP to cancel the transaction. When I asked for a name and numebr to call back to check the validity of the call, they hung up. I proceeded to call Lazada customer service who confirmed no such unauthorised orders and my account was safe. Provided them the details.
