Forcing debit order after cancellation period

iBurst has failed to stop the debit order for 6 months now,<br> 1. They refused to cancel the service for 4 months as we made numerous attempts with their office<br> 2. When they finally agreed to the cancellation they failed to provide the data service as per the contract with me in the last month of October, when they provided NO data volume.<br> 3. They continue to force a debit order on me, creating a continued distrust and therefore the account cannot be settled.<br> Apart from that they sent e mail to my address but address to other clients! Totally unprofessional
