Cancelled but still receiving billing emails

[#1]

I cancelled almost 1 year ago but I am still receiving emails stating that I am going to be billed. I tried calling up but they say I need a pass phrase for the security on the account. I have no idea what passphrase they are after and they refuse to speak to me until i can pass this stage. I have managed to reset my account password for the mobile and I can see bills have been coming off but I cancelled the direct debit 1 year ago and I am concerned this is going to affect my credit history. 

It was certainly cancelled at the time because I migrated the number to a new provider and had to request the pac code. I was on a monthly rolling contract. What are my options?

Thanks for getting in touch @Gregg

I'm sorry to see you're having troubles stopping the billing emails going out.

Could you PM me the following details so I can investigate further?

• Your full name
• Confirm you're the account holder
• Your full address
• Mobile number

You do NOT need a 'pass phrase' and the PN representative should have used alternate checks.

It seems to me whoever told you that in PN needs disciplining if they offered you no alternative.
