inconsistent billing

After being disconnected due to cables being cut during installations via their own contractors installing fibre optics...they credited my account ..and then in the next month my account charges were simply increased to an amount of over 50% of my usual bill. I work long long hours and do not have time to try and contact them..their website is not user friendly and every time I attempt to contact them via \email option"it refuses to submit..I thus am forced to use the website of hellopeter to get answers"
