Xtremebet-Rival bet lost my money

[TWINUNO]

Rivalbet used ot be part of the ongame network before the splits. It then went to it own small network with less then 1k people on it. I had a pending withdrawl for 467 bucks for about 3 months clearly i know I wasn ever gonna get it but at least i could always cancel my pending withdrawl and play or bet sports on it. I then had it pending for two months where i then cancelled it and played and tried again about a month ago.
It then merged with extremebet which i can log on to, it has my player points but it has no free money which i used to and my pending withdrawl is not to be found. I went to support where it tells me to contact rivalbet support but how do i do that from the univeral cashier page they use?
