utilita rep came our door said we had utilita smart meter and if we changed to them we would nt have to pay a standing charge .We said we would change and the rep set the wheels rolling we had a letter to say we would go live on the 12th july 2023 and would be able to top up tried to do this and it would nt let me so i went to visit the utilita shop the staff there were very helpful and explained things had nt gone though and we were on on the link not to worry has we wouldnt be cut off while they sorted out.We went live again on the 12 th aug 2023 then we were able to top up when checking my account on the 2nd sept 2023 we have a debt of £391.39 for the short time we were on the link .I have called and been told this is how much energy we had used from the 12th july till 8th Aug 2023 how can anyone in the summer month use this amount of energy.l
