Avanti are an absolute joke of a company, if you are thinking of moving to them don’t do it. Their business is so poorly run, like others I ran out of gas in the middle of winter despite all the reassurances. Customer service is so poor and they haven’t got a clue what they’re doing- yet of course you are tied in for 2 years. I’ve recently moved to Calor and have had a decent start . Whilst moving, despite me confirming in writing I wanted no more deliveries from avanti - they conveniently tried to fill my tank , fortunately I was there when the lorry arrived to stop them. Still waiting for £1200 cash to be returned and today told it will take another 10-12 days- this was their response this morning. The refund amount is £1,220.17. And you are not able to have it now I’m afraid we have a process to follow and that is how long it takes. Kind regards, Whatever you do - don’t sign up to this incompetent business
