unsatisfied customer

i had the most horrifying experience with clientele , they call me on Wednesday telling me that im about to loose my policy and im shocked then they tell me now my policy is fine only to find out they set up a new policy with a higher premium and lower benefits, when I enquire they give me so many stories, ive been a customer for 6 years and im so disgusted at this treatment , first my policy lapse when I quoted them their rules , the reason changed, now I cancelled my debit order when I send my bank details through that is still not enough I have to now get a letter from my bank stating that I didn't cancel any debit order , really
