I recently received notification that my direct debit for gas was going up from £110 per month to £197 unbelievable so I rang on 6 Dec and was told it had been changed back to £110 and I received a letter to that effect however on 22 Dec £197 was taken out of my account leaving me penniless. When I contacted them they were unable to oblige with a refund and told me to claim it back from my bank and then pay the £110 my new payment of £110 would go out in Jan 2022 They are quick enough to increase payments but it takes a month to reduce them very poor customer service
