Trying to cancel a deceased spouse's contract

<p>My husband passed away on 2 March 2017. I have been trying to cancel his contract since the 4th of March. I have phone Netstar twice and sent them two emails. They have not sent me what they need to cancel the contract yet and they have deducted another payment from our bank account.</p> <p> </p> <p>I also asked them to cancel my contract as I sold my car. They said that they had, but they have deducted another instalment from my bank account.</p>
