Staff are so rude bombarded with emails and phone calls. Was previously on a prepayment meter they told me I owed them money I have been making payments using their automated payment line. Called again today to tell me they have added another £10. Late payment fee (how when I've been paying?) I've refused to give my private bank details over they want to take the payment automatically I declined which is my right I do not have to give my bank details to an energy provider i am no longer with? Very shocked how They are able to get away with speaking to people like this...I will be taking it further if I keep feeling harrased.
