Trying that today.
Someone in customer services answered, transferred me to billing and I got cut off after 7 minutes on hold.
In a situation like this just contact your bank and get them to refund the money under the Direct Debit guarantee.
Completely agree with that.
I think most people don't realise how simple it is to do this and it's no hassle. Claim back your DD fees from the very date you started paying Coms and trust me they will then take notice of you, you are perfectly entitled to do that too. Empower yourself against their dire customer service and stop being a victim.
Once they sort the situation out then it is then up to you to then repay them any monies that are owing if you so wish. i.e. YOU are in the driving seat.
