Terrible experience with Liquid Capital t/a 360 plus

I had a motor service plan with Liquid Capital t/a 360 plus and my experience with them was not nice. I began my plan with them in May 2018 and after about 5 payments they decided to cancel my service plan with them without my concern. My problem started when debit order for the month of October 2018 bounced as there was technical problems with my employer's payroll so my salary was paid on the 27th instead of the 25th. One of their consultant called me on the 10th of November 2018 to arrange for debit order to go off on the 15th and I honestly informed her that I won't any funds available during that period of the month. I asked her to do double debit on the 25th of November and she blatantly refused. To my surprise my policy was cancelled without giving me the client a chance to rectify one month unpaid payment. When I called 360 plus, I was given a lame excuse that their system automatically cancelled my policy and there's nothing they can do. I asked for the copy of the contract which states that when their system cancels a policy then I won't be able to be refunded my premiums as I haven't used their services? Till this day I haven't received any feedback after sending several emails to their customer care. I need all my money back because they failed to provide me with the service that we agreed upon and we never had an agreement to terminate the contract.
