Review I feel have been cheated

I have been cheated. I placed a bet on 9 teams today(1/09/21) with a potential winnings of gbc 440.00. Two of the matches out of the nine ended up being a “refund all”. The other 7 were right outcomes. I was given ghc 80.00 as the whole winnings for that betslip. This is a big cheat. I need to be compensated.
