Read this:
www.productreview.com.au/listings/transdirectCustomer reviews. The interesting thing is there are a lot of positives, but dig a few pages in and you'll see a trend. They don't want to know you after you've paid them your money.
40 rated good to excellent - 67 rated them bad to terrible. 64 overall terrible rating (I will add mine so make that 65) and 32 excellent. What this means is when things go smoothly people are happy. But it would seem that more often than not they are appalling.
I wouldn't be at all surprised if they were the ones putting the positive comments there. Sort of thing a company will do when there is this sort of bad press. Get all your mates to write a positive review and drown out the negatives.
My advice, don't use them.
