Very unhappy client

Iv been waiting for installation that blitz fibre called me for last week and arranged time and date which is today at 8am, it’s now 9:37am, no one is here and no one bothered to call with an update, Iv called their offices a million times this morning and now they’ve ended up killing my call….iv missed work this morning because of this and the least they can do is answer their phone and tell me what’s happening 😤😡
