In June last year, I rang Octopus to tell them they weren't charging me for gas. There had been an inputting error when they set up the smart meter for the gas and the readings were rejected because they appeared nonsensical. It was resolved while I was on the phone and all adjusted and correct on the next bill.
While I was on the phone, I checked when my fixed deal was due to end and explained that I was concerned about affordability when the price cap increased in October. The woman on the phone said that I could commit to fixing for 2 years at the prices then current, but that they could defer starting the new fix until my current one ended in Nov 21. I damn near bit her hand off, I got a fix till Nov 23 at June 21 prices, which is fantastic (although I'm shitting myself about how much it might be by then).
I'm leaving the credit to build up on the account (currently £190-ish) and will leave the extra government payments to build up and increase the credit, which will hopefully ease the impact of nearly 2.5 years worth of increases all in one hit.
I've always found them very helpful on the phone, and knowledgable, and am quite disappointed that some PPs didn't have such a good experience. And they guy who came to install the smart meter was very polite, and rang me when he was leaving his previous visit so that I knew when to expect him.
It sounds rather as though they haven't been able to maintain the same standard of service now that they've got bigger, and presumably busier.
