Sorry for my non responding to all the excellent advice, which by my own admission was a long time ago the delay was because of family issues & the pandemic but my issue has been fully sorted. i have NOW only 1 ADSL master socket as mentioned previously which has been reinstated where it should been. After much aggravation caused by all i can describe as an over zealous BT engineer of many years ago. previously i did say i had 2 master sockets which he incorporated into my system upon inspection in fact i had 3 yes 3 master sockets within my system the third which to be honest i never spotted was in the photo attached. i did say i would show a before after photos but as of yet i have not got round too. Just like to thank anyone & everyone that gave advice
