I SHOULD HAVE CANCELED MY CONTRACT WITH NETSTAR

Three weeks ago I informed NETSTAR that I no longer need the unit as my father is now using the car. I asked that they tranfer ownership to my father and start debitting his account, I even sent them my fathers contact details. After being ghosted and not responded to I sent a reminder and expressly stated that they NOT debit my account anymore. I have just woken up to a debit from Netstar. This is now an unauthorized debit. My 3yrs contract is over I should have rather cancelled than give them continuous business! This is very unprofessional not to add zero customer care. This was really a simple thing. So disappointing.
