Dear Sir,
You """""system"""""for dealing with customers is dreadful.
I purchased a browser last Wednesday 4th and you have taken TWO LOTS of £17.99
from my account on the same day and with the same ref. 01522803205 GB  All I keep
receiving is notes about you not being able to find the account. WHAT IS GOING ON IN AVG.???
