Tripmonster complaint: No contact details to call to

I cancelled my flight to Istanbul on July 5, and my flight is on July 7. There was an email acknowledgement that they will contact me in a few days.

On July 7, 9:40pm, Tripmonster time stanp email is finally arrived. But unfortunately on the night of July 7, I wasn’t feeling well and I slept early. I woke up next day and when I checked my email, I found that Tripmonster is requiring me to re my cancellation by clicking the link which is valid only for 4 hours! So I am already too late! Why they swnding late email and with validity of 4 hours! This is ridiculous. But still I clickef the link and cancelled again creating a new request on July 8, and same I need to wait for them to email me again. And since then, i have been putting my alarm every 3 hours even in the middle of sleep to make sure I won’t miss their email again. 7 days passed, no email from them. I have to do something so I explored the Tripmonster site again and click change booking. There I found a comment box to where I can put my complains. And after few hours. I got an email from their customer service ([email protected]). So using that thread I made a follow up and told what had happened. Then after few hours, Tripmonster sent me a reation link at 2:48am July 16, though I remember checking my email at 3am and that email wasnt there. Anyway so the reation link is now valid for 72 hoirs. But when I saw the amount of my refund, which is unexpectedly low. I booked return tickets at 677$. But I am only entitled for 127$ refund and from.it they will charge cancellation fee! I am confused. Let say i wont be entitled with the passed flight. But my return flight not yet came. They mean to tell me that the flight from IST to MNL only cost 127$? I think Tripmonster is a scammer. Very poor customer service and they are afraid to put their contact details on their site. Because they probably doing these kinds of scheme to get money from people who will cancel their flights. Bad service.
