Hi nutstool
I'm sorry you've had such a bad experience in the short time you were with us. It certainly does sound like a nightmare.
I would make sure the agent dealing with your account has opened a complaint for you. This will prevent the debt follow up brewerdave referred to earlier.
We certainly prefer to use actual meter readings wherever possible. However, in the absence of actual readings we are allowed to use estimates. We try and base these on as much info as possible like any past usage history or details of the property. We're also happy to replace estimates with actual readings at any time.
As maxstream says, it's always advisable to take readings when moving in/out of properties.
When changing supplier, it's the responsibility of the gaining supplier to tell the losing supplier the readings they will use to open the new account. The losing supplier uses the same readings to close the old account. This is to make sure the customer is not charged twice for the same energy.
I don't want to worry you but were the readings we used to open our account back in January the right way round?
This might take a bit of time to sort. You can help speed up the process by taking readings at the same time each day. See which register is moving and tell Scottish Power. This will confirm whether or not the readings they first gave us were, in fact, correct and our original opening readings were the wrong way round. They will pass the details on to us.
Once we've established the correct order, we can re-bill your account the right way round.
Some of this is just pure speculation, though, and I could be wrong. What has resulted is clearly a mess. This is another reason I mentioned opening a complaint. An individual agent needs to take ownership of the problem and escalate through our management structure. This will also speed things up.
I fully understand why you're claiming the money back. There's no way you should be paying an incorrect bill.
Again, I'm sorry you've had such a bad experience. Give me a shout if you need any info as will be happy to help.
