Homeschoice does not want business

I was qualified mid to end of 2019 to buy for R3000. Without anyone telling me it expired and I had to re-apply. I did and now they approved me R2000, same info nothing changed on my profile. I have had someone calling me monthly as to why I have not bought. Now that I found something I really want to buy, it costs R2299, so I am R299 short (One payment). I ask them nicely I email I message I call and NOT ONE PERSON is prepared to even talk to me about this and work it out. They just tell me (from a script) that's what I qualify for. I worked in retail, I understand about helping a customer. Surely they have some kind of contingency to assist on such occasions? I am mad and disappointed. Is business so great that they don't want or need my business? In today's harsh economy. I can't see it. I just wish I could find this particular item somewhere else. I am certainly going to try.
