Netstar not taking Clients serious Bad customer service

very bad customer service I took the tracker when I open my insurance during lockdown I passed my insurance and netstar tried to debit my account and did not find the money and in August I've sent them email twice for change of banking details because the accounts and that I gave them does no longer fall under personal account is a business account after I've send them email I've tried to call them they don't respond to emails and they continue to debit the wrong account even though I've sent them the right account twice in October I contacted them again and give them the right account number on the same day they debited the wrong account number and I send them emails to reverse the debits that they have sent to the wrong account number the two debits and none of their stuff is calling me back they're not unprofessional unprofessional company and I wouldn't even dare to refer anyone to these people they are unprofessional

The following emails are useless *** And ***.z

All I'm asking for is the reversal of to debit that was sent to my business account so that my business account can be clear of debits Ref.Netstar 579516
