Frustrated And Angry

I am so frustrated too much I have financial problems, and I've arranged with Mr Price that I will pay R300 every month until I am financial stable and I am paying that R300 every month, Secondly I know my Mr Price Money is in arrears for only one month but wow my lunch at work is from 12:45 to 14:00 but they busy calling me on my cell during my working hours then if am not answering the Dial my work number, if I was running away or not paying anything every month I do understand they can do that, But this thing of being called at work firstly I can loose my Job then I will stop paying Mr Price. I am very angry and frustrated also about Mr Price they must call me on my lunch break or after work 16:45
