I have made a purchase for some membership to private site and then i'd like to check my account in http://rknethelp.com. So the Site didn't work. and then i've contackted them via online chat to ask them support to check my status. Tey askem me last 8 numbers of my credit card and then sayed that something goes wrong and tehy cannot find my my account, and asked me to call them. I don't know that will happen with my credit card account now. Do they hack my bank account and have they rights to ask a credit card numbers.???
