UNASKED FOR account upgrade!

So I have requested an increase in my credit card limit for my Gold/Aspire account. Received the updated agreement STILL stating that it is in fact for my Gold/Aspire account. So the next morning when I opened my FNB app I've noticed an additional account "FNB Premier Credit Card" Immediately I contacted the bank who informed me that an application was received and has already been approved. I double checked the agreement I have received and NOWHERE it stated that the account has been upgraded. The lady at customer service said that a card needs to be activated before they can downgrade my account, so they activated a premier card on their side. This was on 6 July. On Friday, 9 July I contacted them again to hear about the progress only to here I should give it 2-3 days. Today, 12 July I still have not heard back and received 100eB as Premier Rewards, for something I DID NOT ASK FOR! I normally received 1700+eB so I really feel like this has been a way in order for them to strip me of that benefit. Thanks again FNB!! Really unsatisfied with what has happened and seriously considering moving to a different bank.
