Close my Account!!!!!!!!!!!

On the 27th of March, i requested for my account to be downgraded to GOLD at your branch in Vaal Mall. This was requested but not done, i then called in to your private banking call center which i was told a case was requested on ref CAS-***-86T3L8 for the downgrade and this was 3 weeks ago. To date, no call nor communication from anyone at FNB to assist with this downgrade, then today as i decided to move to Discovery Bank which i still kick myself to coming back to FNB, i called the same call center to notify you to CLOSE MY ACCOUNT! gave the agent the referrence and asked to CLOSE the account. Now i just received a notification that my new card has been ordered, i had a gold service fee go off the account i emptied this morning. I just called again for the 3rd time your call center and am being told, sorry you need to deal with Gold account call center which is BULL****. PLEASE CLOSE YOUR ACCOUNT as i am no longer interested in your pathetic service
