Uprofessional and Poor Service Delivery

I took a contract that was offered through a phone call because I had used Cell C for at least 8 years in 2012. I lost my job and could not maintain consistent instalments. I got my new job and have contacted Cell C head office to enquire about my settlement and request my name to be removed from black listing. I have spoken to consultants who tossed me to and fro their different departments where some would take my enquiry and promise that someone will call me back when no one ever did to date. The store consultants in Braamfontein keep giving me different numbers to try out. Dingani (one of the telephonic consultants) told me they should contact the legal department on my behalf when he also assisted with the balance, but I have spend my own money without a successful professional service as I can not qualify to but a contract phone even after having settled my account with them. I am not impressed or even pleased with Cell C's after sales service, my survey proves that I am not the only one complaining about the degree of incompetence from Cell C as a whole, lest you speak harsh and nasty to its employees then you won't get the help you need. Where is the client oriented spirit?
