Disgusting customer service

I have never received such poor service and disrespect as I got from nedbank. I put money into my credit card. Then when I tried to transfer the amount I could not this was last week Tuesday. I called the card department about it and they told me it would clear after 24 hrs. Tried again the next same problem so when I called they told my account was closes due to being overdrawn. They told me I had to send them proof of my account since I don't bank with the. So I sent them a picture of my card since it has my account number on it and this was Thursday and they had told me it would take three days which I argued as it did not take that long for them to take my money and this was on face book and every time they would reply I have to send my details and they did not care to explain or reason with me as an angry customer. So when I gave in I expected to get the money at least by latest Tuesday but know. I requested to called some guy by the name of mark called and told me that I should have sent a statement and this is why it had not been done. No one cared to let me know till then. I did on Thursday before 10am and by 12pm I sent an email to confirm that I would I would get by Friday 11/07/2019. His reply was that the cut off time had past and as an ex nedbank employee I know cut off time is 11am so I told him I wanted to escalate it and he said I would be contacted at this point it was around 13:00. Till now I have not yet been contacted. I went to my nearest branch to have this dealt with but they said I would have to call from the branch and I spoke to a few people who were basically telling me that I could only get the money I'm about 5 to 10 days and the bast that could be done would be by Monday. I would not except this due to the treatment, unfulfilled promises and disrespect that I have been getting. I was advised that they would try to make a plan and to make it easier I would need to open a savings account but there was no guarantee due to me being under dept review. I did and this manager who tried to be helpful called Marks manager and came back to me saying the transfer was done this morning and could only come through Monday or latest Tuesday. This was done due to my escalating it. This qaa the worst because I escalated because I did not want it on Monday after that had been done but it was like they said "FU its gonna be done this way and we are not even gonna call you." Pathetic... I was given two managers numbers and one does not go through and the second just keeps ringing.
