Finchoice double payment no help from contact centre

Morning I’m so disappointed with finchoice why did you debit my monthly premiums twice ? I paid on the 20th and you debit again on the 25th and that’s money for my electricity bill . I call and there’s basically nothing they can help me with at this point I’m so irritated . I am honestly annoyed with the service . They say it takes 7 days to refund but reviews here show that it’s being more than 20 days waiting for refun . I guess I’ll be with no lights for until god knows when your reps are honestly gonna take your company down. I wish I checked reviews before doing anything with finchoice . I even contacted them before they debited they said they won’t it might be an error and actually did . They say they can’t help me because it has reflect 😭
