I rang o2 customer services for help and they were useless, told me I couldn't do it so I just tried Soweto's suggestion so we'll see if it works, thanks a lot, much appreciated.
On Call log press Reject List - phone shows you all numbers from txt, calls made and received, then you choose the one you want to block- then hit ADD you're done.
