******* *****ing from a pensioner, after cancelling contract.

My gran has cancelled a contract with you guys in May. All was sent through, she paid the early cancellation fee, the sim was moved to a Prepaid service, and now a debit order has been processsed AGAIN! This comes after she previosuly cancelled the contract after it was up for renewal, and you guys just deciided you are renewing it yourselves. What type of ******* are you guys, to ***** like this from a pensioner??? You should be ashamed! ***-5. Resolve this BS!
