Poor Service , Need info on debit order taken

I contacted miway a few times in question of cancellation of my cellphone insurance, i eventually did it online. Now the debit order went off which includes the amount for my cell insurance, yet i received an automated message that it had been cancelled. I have tried multiple times to get hold of you with no avail. Is this how you treat customers whom need to make amendments to their policies ??? Disgusted with the type of service i am receiving!!!
