I used my voucher nearly 2 months ago and contacted kgb deals CS after I hadn't received anything a few weeks later. It took them nearly 2 weeks to get a response from the merchant who said it had been shipped. So I told them again that I hadn't received anything, another several days later they say the merchant shipped a replacement. That was nearly 3 weeks ago so I emailed them again about 6 days ago and haven't received a response. I tried calling them today and all I got was an automated message saying "our advisors are busy helping other customers, please send us an email".
I can't get my money back through my bank because I used PayPal and PayPal won't give me my money back because the 45-day-period has ended.
I use groupon, wowcher, etc all the time but kgb deals has been my worst experience with any online purchase so far.
