Complaint Review: Rapidlink Inc.

I call the Philippines at least 2x a week. Given the frequency look for better deals. I purchased this "MetroLink" prepaid calling card (by RapidLink Inc) in an Asian grocery. Apparently thier cards are available everywhere with different names. It's a $5.00 face value and is equivalent to 35 minutes talk time. Thinking it was such a great deal, i bought 4 cards to try. Below are the actual talk time (as per thier records). They are as follows:

Card #548-0546-259 13mins. = $3.48
#846-6228-066 29mins. = $4.98
#360-0390-576 5mins. = $2.71
#902-2760-746 13mins. = $3.47

All of the calls were unwanted disconnections. The phone line just went dead . They charge $2.12 just for a connection fee and $.082 every minute after. It would be practical to just max out the card. If you notice the above rates are not even consistent with thier "supposed" rates.
I called to complain about the disconnection. I asked them if they could re-instate the connection fee so I can call back the person I was talking to. They cannot look into the account because it takes 12 hours for them to update the system (?). I called back the next day. The cust. rep. said that they cannot issue the credit because they are only responsible for the first 3 mins(?). I even suggested for them to connect me to the other person if they didn't want to give a credit of the connection fee. Suggested maybe the overseas line is faulty. I talked to the supervisor and maybe shed some light to the situation. He couldn't give me an elligible answer, and either dicides to hang-up on me, or thier faulty wire got in the way. Regardless, again I found myself talking to a dead line.
I have tried numerous kinds of pre-paid phone cards. In the rare occassions that I do encounter problems. The phone card company always looks into the situation first, analyzes the problem and then tells me what happened. In this case however, they checked how many mins. I was on the phone and right after that they give a standard and rehearsed rehearsed response.
Remember that this happened 4 out of 4 cards. I tried to log on thier web, no customer complaint or suggestion section.
