bad Attitude and billing

Good morning <br> <br> am currently under a financial problem and am unable to pay full installment for my account i make arrangements every month and it has being collecting without a fail, so these morning i received a call from you guys and couldn't hear the agent and i returned the call only to be answer by Nosizwe who gave me the attitude, she needs to change her telephone etiquette when speaking to your clients, she threaten me about your lawyers , so i know my installment is not up to date but at least am trying , what i want to know is should i have a problem come end of September what should i do, cause really am unable to pay full installment for now and i spoke to most of the agents if you can do a call retrieval i explained that to them, regards, Tumie
