Missing Petron funds in Metamask

I had made 2 withdrawals on Petronpay: 1 for $ 173 and the other for $ 1330. After charges, the 1st $ 155.7 and the 2nd $ 1197. But on my Metamask account, I only saw 0.27054 Petrons. I claim my petrons because I need to exchange them.
I’m counting on your understanding
