40 minutes on hold to Virgin Media while they try to book an engineer to replace a TiVo box that went up in smoke (literally!) 2 weeks ago. Multiple calls to unhlepful staff in the meantime. Honestly, it would be easier to get a GP appointment...
Also GiffGaff. Tried to swap from EE. Nightmare. Massive buyers regret. You defintely get what you pay for.
But in the interest of fairness... First Direct and Octopus Energy are very much on my good list 😀
