Pathetic service from new credit card applications

Pathetic New credit card application validations. I did my application on 8th November, 2018. I was approved for a private clients credit card of R50000. I have sent in documents in support of my application. There was no response for 1 month and then they suspended the application, because apparently i didn't call them to follow up my application. After that I asked them to escalate the application and then on 14th January, 2019 they requested for additional documents. I sent the documents on 15th January and then they received the documents on 16th January and then they started processing the application. Every time i call the call center, they give different answers, one consultant tells that its in fulfillment stage and other say its in validation stage. I asked them to escalate because its more than 2 months i did my application. They escalated it and told me that i am going to get the feedback in 3 to 7 working days. When i called them today, they said the feedback is not received and they going to escalate it again and its going to take 2 more days to get the feedback. Seriously, I am sure the people working in the relevant department are really pathetic and cant do their work. Maybe its the beauty of working in banks in validation department or whatever department that my application is with. On top of it, the Consultants are also very rude, i think they don't like to assist customers, they want a free life at work, yet they getting paid. One thing i hear is its not their problem because they just call center and cant do anything else. Of course all i can see is people who cant take responsibility and every time i want to speak to team lead, then it takes 20 minutes and they never answer. I wonder if there is really proper working team at the credit card applications.
