no reply from cell c - poor service continues

i have 2 contracts with cellc. i took my z3 for repairs in jan 2016. after a fight,i was given a loan phone that doesn not really meet my needs. after a month i called the store to follow up. i was told i need to choose another phone as they dont have Z3 anymore. i refused to accept that. i was then called on 27/02. the lady said she will try to order it by monday only for her to tell me Z3 is discontinued, i will have to take another phone, offering AG, LG,Mocrosoft or J1. i stressed to her i only want blackberry, nothing else. they want me to pay more money for another bb handset whci i cant afford. at this point im so angry because i was waiting for my Z3 as i need to hand in my other contract phone which is not picking up network. ples my first complaint regarding the store manager has not been resolved since the onset of my contract in August, where the manager almost slapped me, called security to throw me out of the store. he still walks proudly in the mall and looks at me like dirt. the manage emnt position should be given to Mbongiwe.she was more helpful to me. from the onset i was not impressed with their services and it just gets worse. im paying for a phone i dont have.
