Terrible service

Pathetic service. I had communicated several times that my bank details changed, yet they still debited the wrong account and my premiums came back as unpaid. Trying to get a hold of someone is a nightmare and when I finally did speak to a consultant, he was rude, arrogant and sighed audibly while I was talking to him as if it was a pain to do his job. When I told him of my poor experience, he did not even attempt to offer any apology or understanding but rather had a very bad attitude. The only reason I decided to go with Discovery, with its inflated prices is because their service had good ratings but my experience has been nothing but poor. Also, I have been trying to find out why for the last 4 months, my premium was a different amount. When asked this simple question a week ago, they just brushed it off as it being my premium anniversary.... Is every month a premium anniversary?! Absolutely shocking how *********** and rude the staff are.
