Were fine until I decided to switch. Unlike other companies they don’t automatically adjust your direct debits. My switch was blocked and I didn’t know why until I contacted avro. I was then faced with an £800 odd pound bill to my surprise. I paid immediately, then thought that was it. A year on - yes one year!! I received a final bill. On questioning it because it seemed odd, I received a very threatening email from the head of bills saying they might get a third party in to retrieve their money. How bizarre is this to send such an email a year on from switching and threatening me with such actions. We of course paid immediately. But please beware, they were fine until... then they were horrible. In my opinion avoid this company they are rotten. I have reported to ombudsman and regulator.
