Help with energy company missed payments
hi, just for some advise if possible please. I moved into a property 22nd April last year. about 6 months later I noticed my credit score take a massive hit from 900s to 300s. After doing some frustrating digging turns out it was due to missing payments with OVO energy. Upon contacting them, they advised that I owe money between 13th April and 23rd April 2025. I responded with a copy of my tenancy agreement showing that I didnt move in until 22nd. they said they'd sort it but now there are more missed payments from OVO it does not appear to be fixed.
raised a dispute with Experian and my bank, but so far nothing. I have worked for years repairing credit rating from a bad marriage. ive asked for it to be removed and my rating restored. is that feasible?
