Incorrect Credit and Petrol card upgrade

I have been a loyal FNB client for more then 20years, on the 23rd of Aug 2018, time: 09:45am. I called FNB credit card division to enquire why my new credit card was not activated. The agent K****tso Maponya was helpful. She then advised me as to why don't I upgrade from my Classic credit to Gold credit and Gold Petro. I asked her about the fee structure and she quoted me R48.00 and R20.00 respective. The benefits was that I would earn double E-buck points on both cards(Credit and Petrol). So I went for the offer. On Monday the 27th of Aug 2018, I got a call from a lady that called to say that, say then see I recently upgraded to the Premier Credit and Petrol Card and therefore need to align my Cheque acc to a Premier as well. I stopped her in her tracks and told her, I agreed to Gold Credit and Petrol and not Premier. I advised her that, she needs to check her records and email the lady that I dealt with on Thursday(23-08-2018) and include her Team leader on the email to contact me about this issue. She advised, that she will do so and get them to call me by 12pm and she herself would also follow. I did not receive ant call by 12pm on the 27th of Aug. At about 1;30pm I got a call from another lady about the same thing, to upgrade my Cheque card from Gold to Premier. I again stopped her in her tracks and told her, I logged a complaint earlier with the lady that called me and she was supposed to get the consultant that assisted me on the 23rd of Aug to make contact with me. I did not receive any call on Monday. So on the 28th of Aug 2018, I called the call centre again and asked to speak to a team leader/manager. My call was taken by a Sundraham Naidoo who introduced himself as the assistant manager, me thinking now my query which turned into a complaint at this point would be resolved. I gave Sundraham, the entire run down of my complaint and that I upgraded to GOLD and nor Premier cards. He gave me his email address just incase to also drop him an email and was assured that he will escalate to the respective team leader that K****tso reports to and get this resolved and he would follow through. At 3:37pm yesterday, I sent Sundraham an email as a reminder about the query and I am awaiting feedback, he read the email at 3:47pm and did not respond nor acknowledge it. This morning I got to work, expecting an email response or a call, to no avail. I called the call centre at 10:30am and asked to speak to a him or a manager, I got told they in meetings and cannot come to the phone. I was adamant with the consultant that I want him to come to the phone. He failed to do that and then another Team Leader Vashkalin Nadasen came to the phone. I again repeated my complaint from the beginning. I said, that he needs to listen to the call and provide feedback today or by tomorrow. So another day's delay. I need to know what is the service delivery to pathetic with First national Bank. No acknowledgement from management team of emails sent. No accountability. FNB your service SUCKS. Extremely disappointed client. I await your feedback on this complaint.
