All I am asking for is someone to please help me

I am a client who is just desperate for someone to assist me. I have come across rude but it is just out of sheer frustration because its always a different story. Kabelo i feel didn't provide good customer service. Despite my attitude there is a way in which you deal with irate clients and his attitude was terrible towards me it actually left me feeling like I've just been interrogated.. I've been trying to resolve this outstanding issue for months now and because of the financial predicament i found myself in i was unable to make the payments as arranged I am not disputing that, I want to sort this out and I asked Kabelo to get someone to call me but i was told to call in 8 minutes and his manager would be available??. Please can i ask that someone who is able to assist me and explain to me in a professional and patient manner to explain to me how we can go about sorting this out. I need to do an urgent sim swap on my contract number and i need to find out what the minimum payment is i can make in order to get a new card as this is my work number and cant afford to have it off longer than it already has been. then to arrange for me to make manual payments to clear my name please.
