Poor service

I am seriously tired of the incompetence and lack of wanting to resolve my enquiry.

I sold my vehicle that has a Netstar device back in March and the new owner filled in the sent forms and sent it to yourselves (Netstar) numerous times but you keep debiting from my account. Till this day no attempt to change ownership of the contract has been attempted, however, you are quick to call me or send an email when I reverse the debit orders.

Please sort out yourselves and change the ownership or I will approach the person ombudsman.
