You are within the lower limits of Impacted on Downstream although Upstream is a little below. You stand little chance of using those to get a visit.

As a Zen voice customer, they will need to arrange the visit however it will be BT that actually arrives (Openreach or OR sub-con). The only other possibility is if your voice circuit is sub-standard - either to low in volume or with too much background noise. Try a little negotiation with Zen ad see if you can get a visit at less than full cost.

I have no idea what the voice quality is like - keep in mind I'm deaf!

I suppose I could try the angle that for me, the quality of the FTTC connection is as important to me as the voice line is for an hearing person and seeing where I get.... (Which is true, I suppose!)

Pester the owner(s) of the building and point out that the utility wiring is an absolute joke, and could easily soon lead to multiple phones not functioning in the event that 999 needed to be dialled from any phone, by anyone (including yours). You could say that you work in IT and know the absolute correct route to get the official/correct people (i.e. Openreach) to put it right, and it will only cost them ~£150*, and no further fuss for them to deal with or arrange.

*Will that be £25+£120 for OR to only sort out Mrdini's line, or will they try to "put right" what's there? I'm starting to assume it'll turn into the £120 visit cost plus £25 per line which needs standardising, won't it? Plus parts, if other people have got setups which include half a socket which was pilfered from Alexander Graham Bell's old house. OK, this is a terrible idae, forget it.

Seriously, I suppose it depends on the building owner/manager. The mess of wires and fact that specific professional tools and skills (and parts) are needed might scare him or her into paying £xxx for it to be all nicely rectified, with repeated mentions of emergency calls for anyone in the building.
