this company is rated a ( F ) with so many complaints.Very poor customer services.

I bought a(Kaser Yofun107-4GB Mambo TouchFlix MP4 $99.99) from Kaser corporation was the mfg.They had my mp4 sence 10-15-08 it's now 2-10-09.I have sent 8 emails and i only got the 1st response back when they received my mp4.I called back on 12-14-08 they said they were sending my mp4 back ,saying there was nothing wrong with it.I had a discussion with someone Name Ken .The guy had the worst freaking customer service i told him i wanted to talk to someone higher than him or a manager and he tells me that his just going to send my mp4 out to me when some other tech takes a look at it.I mentioned that i need to talk to someone now to solve this and then he say's he has to go and hangs up on me that freaking ahole pist the f@ck out of me .I bought this from fry's so beware of the mfg. Kaser they have the worst fu$king customer service.They will not get back to you unless you owe them money .I will report this to the BBB and also to possibly the RIP OF REPORT for sell crappy prod
