No words to describe such terrible service

I think I have received the worst possible service ever from FNB. I have been trying to open an account for the past 3 months. I opened an FNB account telephonically 3 months ago. Due to possible lack of understanding from the consultants I decided to cancel the transaction. About a month ago I spoke to a Manager I unfortunately forgot her name and her department but she tried to convince me to change my mind. I reconsidered and for the past 2 days I have been struggling with the same issue. Yesterday 06/10/2018 I called and was informed the systems are down they took my details and I was promised a call back. Today 07/10/2018 after my call was not returned I decided to call again with better luck but to my dismay it went from bad to worse. I spoke to a lady by the name of Lynn in the sales department who firstly did not sound interested to assist me. I requested to speak to someone else of which I was placed on hold and she did not get back to me. I eventually decided to drop the call and when I called back guess who answered. Yes it was Lynn again. I asked to speak to her Manager and this time around she dropped the call on me. I called back and guess who. Of course you are right it's Lynn again. I once more requested to speak to her Manager and she called a Team leader by the name of Victor. I politely asked Victor to speak to a Manager and he referred me back to Lynn. Talk about climbing the corporate ladder, if by then Lynn was a Manager she jumped over the corporate ladder. I then called back on numerous occasions spending almost 45 minutes on the combined calls with the likes of Mzwaleni who arrogantly told me that he is going to drop the call and did so. Then I spoke to a Yana asked to be transferred to the complaints department and she transferred me to lost / ****** card department. I then finally got through to a Latino Beukes talk about unprofessional. I think FNB employs the worst Call centre agents in South Africa. Latino whispers to the person next to him whilst I am on the line and quoted "I think this guy is trying to be difficult". If this is the type of service a potential customer gets from a FNB, I feel sorry for their existing customers because based on my experience I can only imagine what others goes through.
