I wouldn't even give them 1 star if I could. On the ridiculous prices I paid my final bill then moved go British Gas. On doing so I got a bill of £400 and when I queried it because I had always paid on time, they said it was due to a billing error where they hadn't been charging me correctly. Unfortunately when this happened I had recently had a stroke and said I was in no position to pay it in full or immediately. I got advice regarding it and had been throwing money at it as and when I am able to do so. Regardless I've been getting daily calls,messages and emails hounding me even though they know of my circumstances and that I am frequently paying. My partner who doesn't live with me rang up and went mental at them explaining the situation and how I was advised it was unreasonable to spam me as they were. The person who took the call said she would put a 3 month block on all calls/messages/emails and once that had passed I could get in touch if if it started again. 3 months has passed and it has all started again, I've had to turn off my voicemail as I was getting automated messages left and multiple daily calls. Texts off a withheld number from OVO Energy and one email that slipped through the net claiming I was expected to pay the amount in full on the 25th of April and if I don't pay my details will be passed on. I used the chat feature and told the person what had previously been discussed, my current situation and that I was paying. And he asked if I wanted to pay the remainder in full..to which I said that's not why I got in touch as I am paying. Then he said unless I set up a payment plan or pay off the money owed the texts/emails/calls won't stop. I wouldn't recommend ovo to anyone ever. Please avoid.
