Yeah, they’re shit
They are the only provider whose signal I can actually get at home – I’ve dumped them all the same
They have an offshoot (forget the name) selling apparently cheaper contracts that I briefly used for one of my kids. They overcharged me, even after me calling up and having a cap put on her account.
Getting an account cancelled took me 90 minutes on a voda account and over 2hrs for the other lot (though, amazingly, the final obverseas call centre bloke I spoke to said “yes, the cap is very clear on this account; you’ve been overcharged. I will refund immediately, hold ther line. And he did 😯 )
