I was overcharged on my March bill due to a technical error in which "some number ranges were incorrectly defined as special numbers and customer was charged for the same special number charges."
I had to spot this myself by going through my bill, then contacting Three support myself. Customer Support told me about the mistake, and told me I would have an adjustment applied to my account - which I understood to mean credit to the amount overcharged.
However, when the next bill (at my regular amount) was due, instead of being taken from credit on my account, my bank account was charged.
So i reopened the case I had initially opened, to be told that the adjustment hadn't been made at the first time of asking but definitely owuld be now.
Of course, the same thing has happened again.
Has anyone else found this issue, and struggled to get a resolution? I'm out of pocket and fuming.
