The worst company I have ever used for anything including all business utility companies too! I currently have 3 complaints with them, one with the ombudsman! All separate issues within only 4 months! They have not managed to do a single thing I have asked from basic change my phone number, to not actually cancelling my account when asked and trying to charge me without permission to do so. It never takes less than an hour minimum to sort any issue out and if you dare to fall into arrears with them they will ask you to do a payment plan review every month, not refund you any money they take from you even if they had no authority to take it. This is a company absent of any and all ethics morals and values.
