Who Is Phoning Me from This Number Repeatedly? – How to Stop It
If someone is phoning you repeatedly from a number you don't recognise, search it here first to understand what you're dealing with. Most repeat callers fall into one of these categories:
Cold callers and telemarketing
If you're on the Telephone Preference Service (TPS) register and a company is calling anyway, they're breaking the law. Report them to the ICO at ico.org.uk with the number, date, time and what was said. The ICO can impose fines up to £500,000.
Debt collection agencies
If you have an outstanding debt, agencies will call repeatedly. You can request they communicate only in writing – this request must be honoured. Search the number to confirm the agency's name, then deal with the debt in writing through regulated channels.
Automated dialling systems
Many calls from unknown numbers are from automated outbound diallers that connect you to an agent only if you answer and stay on the line. Simply not answering eventually removes your number from the active list. If calls are unwanted and persistent, block the number on your phone.
How to block repeat callers
On most smartphones: go to your recent calls, tap the number, and select Block. On a BT landline, the 1572 service provides call blocking. Your provider can also add Anonymous Call Rejection (ACR) which blocks calls from withheld numbers.
