So you have a problem with your voice service and/or broadband service and need to contact your ISP. They get you to run some tests which frequently require you to expose the hidden outlet of the master socket. Additionally thy may want you to contact you by your mobile while tests are carried out on the line.
This time around there is so much noise on the line that a) it is difficult to hold a telephone conversation and b) the broadband service keeps on dropping out.
So for starters you are asked to change the ADSL filter and some times asked to use another router, as if the average Joe public has one lying around! Frustrated with all this my neighbour asked me for help.
Well there is no master socket and to compound the issue further, mobiles don't work in the property. Our Indian friends don't seem to be able to escalate the issue further for a resolution but instead go down the tack of getting an engineering out that would cost megabucks [well to a pensioner at least] to 'fix' the problem.
So any suggestions here to get a nice crisp line and a broadband service that stays up and therefore fit for purpose for free? Short of fitting a new master socket myself, and being carted off to jail for doing so, I don't see a way forward.
