Contract was cancelled - still being debited

<p>My dad had a contract with glocell that expired in Nov 16. He received a confirmation letter regarding the end of contract. The reference number is ********** 5. To date he is being billed the full amount via debit order. The bank says the debit order can only be cancelled via glocell. Glocell continues to make my dad run around in cricles. Kindly remove the debit order and stop billing him for a contract he no longer has. Glocell customer service is dismal. It should not be the client's responsibility to waste further money and his time resolving this when the error is on the side of glocell.</p>
