Travel Discount Cards

I love traveling ( who doesn't? ). With airasia getting cheaper, lots of promotions... and the lovely MATTA  fair. I always go there, just to check out any great offerings. But year after year, there's always some booth which offer discount cards for accommodation, flights, and so on. Can they be trusted? I'm just saying this coz i got conned once, at plaza alam sentral shah alam. Their company name is slyways travel. The supervisors name is Idrus. They say they offer up to 70% on selected hotels nationwide. Well, of course this got my attention, as i was planning to go to langkawi in 2 month time.
So there I was, listening to his explanation, bla bla bla.... which got be really exited at that time. So, i asked him for a quotation if i wanted to go stay at Berjaya Langkawi Resort, so i can survey 1st the price. He said he cant give me because its company policy that only members can request quotations. I didnt think much at that time so i paid the scum rm350, and became a member right away. He said if im not satisfied with the quotation, i can cancel my membership and get a full refund within 7 days from i signed. So ok, thats a fair deal.
The next day noon, I got my requested quots. Then i surveyed in the net, to my surprise, not only is it not cheaper... but and extra RM800, wtf?!!.
I called this Idrus guy and so we meet. I printed out the prices i got online and compared it to his so called cheaper quots. He reacted very calmly like he was expecting this. And so, I requested my membership canceled, and a full refund. He said no problem, the process would take 3 days.
3 days passed, no news. Ok, maybe its not ready yet, im a patient man :). Day 4, noon.. still no news. So i called him, he said the person in charge of the account is on leave, Ok then. The next day, he said he didnt have the time to go back to the office. So fine, I'll just go then. Well at that point he was making excuses not for me to go. In my experience, people who give excuses 3 times in a row for the same thing is someone not to be trusted.
On the phone i said ok, but without wasting anytime, i went to Alam Sentral to confront him. Well he was surprised to see me. I said in a loud voice so everyone can here me, wheres my refund??. Well, there was more excuses coming, i think the guy has a book with all the excuses in the world. He promised me the next day the money will be transferred to my account.
Unfortunately, the next day i had to go to a seminar in PD for 3 days. After i got back from PD, i checked my account, there was no RM350 transferred. I called Idrus, he switched off the phone. Just my luck, so i went to Alam Sentral, the booth is not there anymore, it seems they closed the booth 3 days ago. So i went to their office at sri rampai KL. Well, it shouldn't be a surprise to me, the office is empty.
I googled the company and found that i was not the only one got conned.
So, its already been 3 years now, since that incident, i dont trust any discount cards anymore. If you people out there comes across this Idrus guy from Slyways Travel, do inform me. A lot of people is searching for him, and be careful when you hear any offer thats to good to be true...thanks.
