Got the link to my email from cslinks.co.uk though initially I doubted is legit till I saw comments posted of those who are benefiting. I right away submitted and paid up $129 through Visa but then, despite receiving membership confirmation, I got nowhere!
We use them to book cscs test and card for our workers - they have slow refund policy which is 7 days but they have very good customer service and they are officially recognized body. Can strongly recommend them...Cheers !
