Scammed my PayPal and I don't even know TopUp...
If this is the same website that just scammed me through paypal, then yes they are a scam. I've never even heard of TopUp before and somehow I got 9 random fraud payments, all of $18.73 from them that went through my paypal and extracted from my bank account. All the payments say "TopUp" on them when i have never even heard of, or done business with them, ever. Currently trying to resolve it and get refunded... if this is the same company, they should really be exposed.
