Do not use this website. This is made only to make you to subscribe for office-pdf.com website, which cost £39.90 per month. I had already 2 attempts to charge me that amount. I didn’t even understand why I’m I suppose to pay for this website subscription, because I was sure I didn’t subscribe. Then I realised that this is a scam strategy from Braintety, which they sell you the IQ certificate for £0.50, but when you buy it, you automatically are subscribed for high monthly subscriptions from other websites. What a rubbish strategy to make money. This website should be closed down
