FAIL TO CLOSE ACCOUNT AFTER MIGRATION

I have migrated my cell phone from MTN to another service provider in the beginning of August. I was happy to pay the bill for August as I know they bill in arrears. I have received cell phone bills at the end of September and October. I have tried to rectify this situation by visiting the MTN Brooklyn branch twice and have sent various e-mails to their Customer care with no luck. I cannot use the helpline as my number no loner exist!! I also cannot phone the MTN Brooklyn Customer Care service branch as they apparently don't have landlines! <br> How can you bill me for a number that doesn't exist!!!!???? I want a refund and confirmation that no further debit orders will be processed against my bank account. Refer to *** or USD ***. I have proof of my visits and e-mails.
