Dishonest customer service - was told by phone that I had no outstanding balance and my 12 set monthly payments had covered my consumption. Pleasantly surprised I renewed my contract for another 12 months with similar unit prices only to be told 1 month into the contract that my gas & electricity monthly bill payment has gone up by €70 because I did in fact have an outstanding balance of €450. Even an additional €70 per month over 12 months doesn't make sense to me as this adds up to €840.
