***** business by Hollard (funeral policy)

I have a funeral policy with Hollard and for the past 2 months i have been getting texts that my debit order didn't go through but when i check my account it shows that they have debited the account. i called them only to be told that yes the money has been received but then i am told to call after 7 days if i want to check debit orders, but they can send me an sms a day after my debit order date to claim that i have missed my debit order. i have a serious problem with Hollard because the other day i received a letter for a new policy that i never took out and when i called i am told that they made a mistake and took out the policy for me. i don't know what kind of a funny business is that but i have lost all confidence in Hollard and i will never advise anyone to do business with them.
