What hope is there of OVO energy dealing with a simple billing / direct debit payment issue based on incorrect SSE migration readings to OVO in November 2022. The OVO call handler dealing with my call based in South Africa informed me that the VAT rate on domestic supply in the UK is 15 percent. I informed the call handler that the VAT rate on domestic electricity supply is 5 percent VAT & felt disbelief that the handler did not know this basic fact, notwithstanding the response was that my Monthly Direct Debit needs to be increased by £110 a month to cover this supposed VAT increase along with the incorrect migration reading. “Fortunately all calls are recorded for quality & training purposes”. OVO need to deal with fact & not fiction & properly train call handlers to deal with fact & manage customer dissatisfaction. My complaint was & still is mis-managed in a cavalier fashion in which clients are mistreated & disbelieved.
