Just because you have a ex directory number does NOT mean you will not get calls from the call centres that scam you. All they do is use an auto dialer device with software that can be programmed to dial numbers in a given range, IE 01946 000001 to 01946 999999. They can also give out random numbers to fool the anonymous caller systems. As you can see they can cover every number. They can also do the same for mobile numbers as well. The area codes for the uk are freely available on the internet and you can bet they share them from centre to centre. So just because you suddenly start getting calls does not mean your number has been found from a hack of a server but it could be because someone is using a dialer and software
