I will first of all say I'm sorry if this post is in the incorrect place, I wasn't sure we're to put it!
My issue is that I visited the dentist a couple of months ago to have a filling. They charged me 36.50 at the time and I was told that was the full cost of the treatment. My dentist said nothing as usual and just did the work.
I have since been contacted asking for a further 18.80 as I was charged incorrectly. I have said that I don't believe I should pay this as I was told the cost at the time was 36.50 and have paid that in full. They are now chasing me for this money an
