Billing question

Why are you trying to extract funds from my bank account before the actual due date? This is the 4th time it's happened and it is the last time it will happen or I will cancel.  I have tried every time you pull this stunt to explain that I get two checks a month, ON THE 3RD OF EVERY MONTH!!! So please don't try taking the funds until the 3rd.  And lastly,  why is wifi dropping out late in the night, like almost every night around 2 AM. It happens 3 or more times about 4 times in a week.  Not happy about that either.
