Can someone change the payment address without knowing your 4 digit pin?
Nope
Can you please help me find out where's 5eth gone from my account on MPH?
Did your payment address change?
You can explore every transaction at Transactions page. Filter Debit types and you will see each of them.
Tell me your id or id num, then I'll look into it.

My payment address changed and there was a MP followed by a series of AP. Initially I had my payment treshold at zero and I was doing MP, but after the address was changed, the treshold was set to 0.01. Thank you for your support.
