Incorrect billing after policy change

I am completely unhappy with the way my policy has been handled. I called on the 05th Oct to amend my policy household to R250 000 and this then reduced my premium. I received the amended policy documents via email. But to my surprise i look on line this morning and my household has been reverted to R120 000. I called to inquire about this only to be informed that what i was sent was a quote. When i look on the documentation no where is it written quotation it is the actual amended policy. This is now going to affect my vitality rewards as i had increased my contents cover to qualify for 50% only to be told that i still qualify for 25%. This is totally unacceptable. I did everything on my part. Who from Discovery didnt do their part???????
