Disappointed in RCS

I have a current loan with RCS and never skip a payment. So I app**** for a re-advance loan on Friday to top up my current one to pay my sons university registration fees. I e-mailed them on Teusday and never received a call - back, so I phoned them on Friday to apply. The declined my application. So I phoned them to find out why and OMW, what a rude person. I try to explain to her the reason for the loan and she just shout "NO - it's declined". So I asked her why and she explain, because then I'm over indebt. I told her I understand, but can we decreased (they offered me R 45 000) the amount just back to R 7500.00 (I need R 8720) and she shout at me again. I was so upset and embarrass that I only put the phone down. I couldn't believe that such a rude person can work with customers. I felt like a ********, just trying to asked for help. I shall never refer RCS to any of my friends or family. I never had problems in the past, but this was just too much. What happen Saturday ?? They call me again and offer me a re-advanced loan again. So I just calmly told the guy that my previous request was declined. Sorry RCS - I'm going to pay my loan in full and then I'm finished with you people.
