Poor customer service

2 months later and my contract is still on going and now the payment has increased without any consent given! No one can call me back, no one can help me, 3 shop visits later and about 5 phone calls this week alone. To what end does a client need to go in order to get proper customer service. Staff that are just unwilling and unbothered to help. Call center agents that have sense of urgency and are seemingly forever with systems down or lunch excuses? All I need to do is get this contract cancelled, which by the way the cancellation fee has already been paid in september 2020.
