I LARTed a taxifirm#2 who repeatedly hung up on my TextRelay call last week and then only reluctantly stayed on the line cos I threatened them with legal action. I'd have let the hangups and hassle drop except their calltaker closed the call by telling me I had wasted his time so I let rip to their info@ email address!
I got a reply today from the manager apologising, claiming he's met every single calltaker 1:1 and trained them about TextRelay, offering to register my number as 'extra support needed' and generally apologising for the calltaker's ignorance and mistakes as well as their unprofessional rudeness.
I think I call that a win. I just need to edit the printout for taxifirm#1 who I wish to make a similar complaint to for not even staying on the line line enough to take my call who don't have a non-postal contact.
