I had very bad experience with CompAsia
If you check previous reviews, they are either five star or one star, with only two exceptions of three and four star. This is exactly what you can expect. You get a cheap product. Either you win or lose. If you get a working decent mobile/tab, then you are happy with the deal. Highly likely that you may not get a working mobile/tab, then you lose all money spend. In my experience their support is pathetic. Fist I purchased a Samsung mobile. This was working. So, I liked the idea and purchased second time. This time it went wrong. They listed the Samsung A7 tab and mentioned that this supports Nano SIM. However, they sent a tab that does not support any SIM card. Now this tab is a waste of money. I cannot use the tab. I feel scammed. Since then, until now I had 75 email exchanges with their support. Some responses are completely irrelevant. Some are out of context. They rarely reply to the point. I felt I am being harassed. You may take risk and buy from them at your own risk. I have been writing them every day for last three weeks, without any luck. If you have endless time, effort, and money you can try this company. I cannot find any number to call them. You are not likely to go to court to get justice for a cell phone or tab. That would be too much to get justice. Only option left for me is possibly "small claim court Singapore". I have proof/evidence of all I have mentioned here. I can provide screen shot, email to support my point. However, it is too much to go to a court just to get back my money. If you can go this this extent in case, you feel you are scammed/cheated then you can take the risk.
