Error in submitting meter reading resulted in incorrect billing. Instead of consuming 44 cubic meters in the period Thames Water billed my account for consuming 440 cubic meters. Billed £1200!! The problem raised to Thames Water in August 2020. Followed up multiple times until December 2020. Thames Water claimed the dispute was submitted to their Dispute team for investigation. At least on three occasions promised to resolve the issue within 10 working days. However, to this day the issue remains. In December 2020 a case manager confirmed the issue was a mistake and gave assurance it would be fixed within three working days. To this day the error has not been fixed. Furthermore, a new billing was received in January 2021 with some strangers name and different account number requesting payment for water consumption at my address. Also, in a week of 11 to 18 January 2021 I received 6 different billings for water consumption at my address. I'm still waiting for a reply and solution!!
