Ok, I may be thick and not know a lot but I've just been shouted and had the phone slammed down on me. I got "this telephone number is registered with the corporate telephone preference service (CTPS) you are breaking the law". Unwittingly I may have, after looking online, and I didn't mean to I found the said company online and nowhere did it say "registered with the CTPS" so am I in the wrong? I've genuinely never come across this before. Does anyone know anything about this who can educate me? Also seeing as it's free to register to this CTPS is it also free to check businesses? I will be doing if so as I don't want to get in trouble and exactly what trouble would I get in?
