Do Not Insure with Csurance

CSurance is one *** service. After notifying them that my bank details have changed last September, they did not debit my account and did not even notify me. I called and asked why they did not debit and the was no clear answer, so I offered to pay manually. October 2014 same thing happens again and this time I was notified that my banking details where captured incorrectly and I gave the agent my correct details and I had to pay manually again. November 2014 same old story of the past two months happens and no I was told the reason they did not debit is because their debits bounced back the past two months, which was not my doing cause they captured the wrong details. Way forward I was told to pay manually. Same thing happens in December 2014 and January 2015, when I was told my insurance has lapsed. After manually paying for the past five months and the problem being them capturing information wrong I was told my contract has lapsed, yet I have been making monthly payments how can it lapse. The contract we reinstated in February 20145 but I had to start from scratch and I was told they will debit on the 15 March 2015. its 31 March no debit has gone through and they never answer
