Terrible, I've been trying to get through for weeks, been told when phone up by the worst automated call system in the world that if I have an emergency to say that and I'll be put through, otherwise if I have not got covid and its not an emergency you are on your own. So I shout the word emergency, and tell it yes I have an emergency. Then it takes me through the process and at the end say "good bye we are unable to deal with your call". They are constantly making errors on my bill with random credits then debits to balance, with no real explanation on there.
