Long standing problems with this company. Always question meter reading, demanding photographic proof and sending meter reader the day after I send readings to confirm. Then ignore my readings and send an estimated bill. Finally decided to switch and then real problems started. Sent letter increasing direct debit (based on their estimates) when they knew I was switching, sent an inaccurate bill which I queried and sent further photos to prove readings, sent a letter with inaccurate charges, contacted and explained, sent final bill, PAID final bill, sent demand for payment of final bill (which was paid), sent a letter demanding payment of inaccurate bill (they said it had been rectified) with threat of referring to Credit Collection Agency. Called but no one available as they all go home early. Now all I can do is wait for the Debt Collectors to pound on my door.
