FNB Treating client fairly

I am extremely frustrated with FNB, an I amazed at how FNB managed to get away with this.

So I had a student account, and I want to add that this was my first bank account which means that I am a extremely loyal client for the last 10 to 15 years.

I started working early this year and I only have my student account so my salary was deposited into this account. FNB then decided to upgrade my account to a private client account without contacting me to inform me of their decision. My bank fees is now almost R500 per month.

I would really like to know how is it possible to do this how can you change a client's product offering with no contact, how is that (TCF) TREATING CLIENTS FAIRLY,

There was no options explained to my there was no comparison done in fees and what would fit me as a client the best.

This is extremely unprofessional and to say the least this product is extremely pricey.

I can't wait to see FNB response on this.
