You will receive an automated call claiming to be from TalkTalk advising you have a problem with your service and to press 1 to be connected to an Engineer. If you then press 1 you will be connected to a premium rate number which charges you a high premium price on the phone bill. If you receive a call from TalkTalk and are in doubt, just hang up and call us back from your home phone by dialling 150. You can also make an enquiry with the PSA about premium charges.
