No business?

Ignorance, no response to emailed queries, wrongful debit orders, backhanded dealing with debt collectors, what more can a company's employees inflict on it; or is it self-inflicted. Netstar does not have a functional customer service which can respond to mailed queries. Its employees are not equipped to answer simple questions. It uses unallowed tactics to collect fees that do not belong to them. This continues since February 2022, ongoing. This is the 1st time I had to mention lack of service here, regarding any company dealt with over many years. Does it deserve any further business from anyone? Could there be a way to get this non-business away from me and never deal with it again? Please advise
