To judge if you have been unfairly charged, the dates need to be less vague, bless you are switching providers using the approved method, just ‘cancelling’ requires a 30 day notice ( that you are billed for ) …if this notice were given in ‘October’ then the month of ‘November’ is the notice period , this assumes the notice was given 31st October, obviously the exact date is required to know when the 30 days are up .
Automatic bills are just that , automatically created , and often will the original billing cycle , so you pay for some days after the cessation of service ( upto the original bill date ) but have those days refunded after the final bill is calculated.
You saying you were billed for the last 3 months of the contract, why is that wrong ? , if you leave early you pay up-to the end of the original minimum term , unless you were specifically told you wouldn’t be charged any early termination charges .
Not paying and not calling to query the amount only leads to negative credit file entries and potentially the debt is sold to recovery businesses, who add on more to the debt for their administrative involvement, you should really call and discuss how the amount was arrived at ….at first glance these invoices are difficult to interpret.
