Our relationship is broken

I am very disappointed. I app**** for a increase in my overdraft to R10,000.00 initially on the 26th June 2019. I sent the payslips to the consultant and heard nothing further. I sent a reminder on 28/06/2019 and received no reply. On 01/07/2019 I received a reply that the consultant PC was broken and needed to be fixed I again resent my payslips as she said she could open it. On 03/07/2019 I sent an email to ask if everything was ok no reply. I then got a email 05/07/2019 with the formal application form and sent it back on the same day. On 08/07/2019 I got an email to say she is waiting for the contract and will let me know later the day, On 09/07/2019 I sent an email asking for an update no reply. I sent another email on 10th and 11th July 2019 and was told there is a backlog in JHB and that it affects more than one client. On 12/07/2019 I got an email to ask for employment confirmation??? I handed in the document and sent an email to ask if acceptable. On 15/07/2019 I was asked to come in and sign the papers so that the limit could be loaded. I went in at the time agreed to waited 45 mins to see the consultant and at the end of the day got a mail to say the limit was loaded. I checked and it was R8k. I immediately sent an email to say that it was the wrong amount and followed up with a call. the call wasn't returned and neither was the email acknowledged. I then sent another email 16/07/2019 begging for an answer and the consultant asked for patience till end of day to sort out. Since then no communication. Today I was frustrated walked into the bank and happened to bump into her. All she said was that credit said that that was all I qualified for and that I can try again in 30 days??? She didn't call me didn't mail me just happened to tell me. I am frustrated and angry and disappointed. I know that I have more funds coming in than before as my daughter pays me rent of R3000 and my income has increased since the overdraft was granted. Nedbank has been my partner with whatever I needed to do however the relationship is broken. My salary and my husbands salary goes into my account and my daughter who just graduated wants to upgrade her account to Professional Banking since she has a honours degree. That would be a longterm relationship based on my association with you. It isn't just about the overdraft. Its about the relationship with my family. My whole life is with you yet you cant see your way clear to grant me R10k instead of $8k. This is the worst service I ever ever got.
