FRAUD FRAUD FRAUD FRAUD!!!

This is definitely a fraudulent company. On Tuesday the 31st of October, this company unlawfully put a debit order through on my account. At no stage did i sign nor agreed to any extra debit orders going through on my account. I need to know who gave you the right to debit my account? i called them and the phone just ring unanswered, i eventually got through this afternoon (02-11-2017) and i spoke to a lady that then quickly put me through to her "manager", the manager, was so quick to put the blame on the call center, telling me the call center is apparently outsourced and they will investigate blah blah blah blah - question is, what is i ddnt check my statement or i ddnt have sms notification? that makes one wonder how long has this been going on for???
