During an abortive and unnecessary visit to fix a BB issue, Openreach engs. took it into their heads to fit a filtered faceplate just because it was more up-to-date and more cosmetic. Since then it has caused a noise on my phone which can be eliminated by interposing a dangly filter, but that rather defeats the purpose. So I want to restore a Split Faceplate, which was OK in the first place, but ISP won't resend engs. to remedy. So I've told them to send one which I will fit.
