Refuse credit application- Afrikaans bankstatement

I went to Incredible Connection Baywest in Port Elizabeth yesterday 7 Feb 2016. They had the laptop in stock that I wanted to purchase, but they were advertising it for R4799 on the web site and in store it was R4999. Their excuse was that it is the online price? I wanted to purchase it on credit, but they could not help me because they are waiting for their credit application system to be activated since December 2015. (I did not want to apply for credit on RCS or Vodacom) So Baywest Incredible Connection advised me to go to the Greenacres branch. So off I went to Greenacres. When I came at Greenacres Incredible Connection, they were out of stock. I asked them can I apply for the credit so long. When the lady went through my info she complained that my bank statement was in Afrikaans and that the one month's income on my bank statement was R500 more than on my payslip. I explained to her that my employer reimbursed me for an office expense that I paid that month out of my own pocket. She did not accept this. She refused to assist me further and told me to provide her with an English bank statement next time.
