If I could give less than one star I would. I recently moved from Ovo to another supplier after months of trying to sort out my Direct Debit payments. My monthly amount kept going up although I was £1000 in credit. I finally moved my account, and asked for a final bill and refund which took almost three months and three complaints to Ovo and a threat to contact the Energy Ombudsman. A complaint handler deemed that Ovo had failed in its agreed response times in my case and gave me a £40 compensatory payment. All done you would think? Oh no, not at all. Today I received a letter saying they were to take me to a debt collection agency as I have an unpaid amount on my bill. I am beyond frustrated and have never dealt with such incompetence from any organisation previously. I now have to contact the Energy Ombudsman with a full complaint to avoid being blacklisted when they already stated my bill had been fully settled. If new customers are reading this, please save your sanity and avoid this company at all costs. If you’re already stuck with them, my advice is to move asap. Unbelievable!
