This would be a zero star review if possible. My late mother was ab Avro customer. I notified Avro of her passing some 6 moths ago, completed the "change of tenancy form" (sympathetic of them to require that form when transferring the account to the executors) and requested the repayment of the several hundred pound balance. To date they have not repaid, and continue to issue estimated bills based on my mother's consumption despite the flat being empty. In 12 months since she passed, zero units of gas has been used, but every month the estimate is as if my late mother (who always had the thermostat up high) is still living there. Similarly with the electricity usage, although we are using perhaps 20% of the old usage for estate agent viewings etc. I have asked a dozen times for current usage to be used for estimates, so that I do not need to do an hour round trip to take readings, Avro have flatly refused. They have had sight of the death certificate and are aware of the 5 or 6 readings I have supplied, but claim that they are unable to reflect the empty status of the flat in their calculations. I have tried to speak to them, but they will only discuss emergencies over the phone. I have emailed, as requested, and they do not reply. If I owed Avro money, not the other way round, I am sure they would be responding, seeking to agree the usage and dealing with me, but instead I have been proactively ignored. Don't let your parents sign up as customers!
