Dissatisfaction

I'm fortunate Dlamini(***) I have a cellphone contract with the company and I'm currently on maternity leave I tried to call so I can make payment arrangements and I was always told someone will call me back until yesterday when I spoke to a lady who told me they do not make payment arrangements when you on maternity leave so I asked her since I don't have any source of income and I will only be depending on the uif so how are we gonna work she told me she wasn't sure. I'm really not happy with the company right now
