Very very poor. I had no bills or communication from shell after they took over previous post office broadband I tried logging into my post office account to pay my monthly fee. I could not log in as this was no longer available, clearly they had changed to shell , I had no notification. I was then sent a text message some months later saying I owed 3 months broadband payments. I couldn't pay the three months in one payment so I phoned up. It was impossible to be put through to a human when phoning up multiple times. I sent an email to customer service on 22/4/22 I am yet to have any response to date 24/5/22. Very very poor !!
