Bad Poor Customer Service

I had just been to Ackermans to open an account,gave all my details and was told if you get approved its immediate,and that was one of the reasons why I thought let me open the account from the first place.So we had to call Cape town were I stood for like 20min before they can take your call,The lady who was assisting me was very rude did not introduce herself just said ''How can I assist''okay I let that slide and continued with the conversation,I told her Im hoping my account get approved immediately as advised on the counter,She circastically laughed and said no you need to allow 24hours I then gave the phone to the guy on the counter because Im now getting different information from both peopl who work for the same store,as soon as she was done with the guy they passed over the phone to me again,she then shouted ''Why did you give the phone to the guy 3 times'',that is when I was started reacting and told her I would have her reported,I don't understand if this is normal service for Ackermans but its purely appalling if this is how you treat your customers.If you use such tones with customers and it you consultants always get away with such,I was really disappointed to have received such bad customer service,I would like you to deal with this accordingly and I would like to get an update before I take this to other platforms.This happened at Midrand Halfway House,08.11.2018 call was around 02h00-04h00 Im not too sure about the time,The name of the girl was Daversney or D-something Im not too sure,and my application was declined,she probably has the powers to do so after telling her I would escalate her I was very suprised to have been declined with such a stable credit record 598 thats my score
