De*****ed by clientele

I met a clientel agent at the taxi rank and she took my details and said to me someone will call me back within 3 working days to give me options and explain what the covers entails the next thing my account was debited on 25 February without anyone calling me. Then i emailed clientele and explain what has happened and they promise me that someone will call me back within 3 working days and no one called, second debit order went through again on 25 March and i send another email and i got respose and they asked gor my details and i send them back. No one called still and i decided to call the call centre and explain what has happened and the agent said to me that i should have reported the matter as soon as the 1st debit went through and i said to her i send an email immediately after the went through and she said they will cancel the cover and it will take 31 days for the cover to be cancelled and i said to her that means another debit will go through and she said yes, i said to her that's ***** as the cover was activated without my approval. She said i won't get a refund as i was supposed to report the matter sooner
