Cancellation of a contract with Netstar

I received an sms requesting that i pay an outstanding amount for car track. At the time I already terminated the contract of the insurance company linked to Netstar.

I wrote them an email and also requested cancellation of the contract, they mentioned that I need to settle the due amount first before they can terminated the contract. I paid the amount and also sent the proof of payment, then requested the cancellation.

To my surprise today 2022-06-15 I received yet another sms requesting me that I need to make a payment to Netstar.
