No service

No service - Arrear fees was incorrectly charged to our accounts (on 13/01/2023. The accounts were not in arrears, their accounts department didn't allocate all the payments. We requested by email on 24/02/2023 that they reverse the fees. We followup up by email on 27/03/2023, 24/04/2023, 03/05/2023 and 25/07/2023. It is more than five months down the line and nothing was done! The other issue is that they mostly don't even bother to reply to an email!
