Disgusting and very poor and bad attitude service

I just had a new contract with cell c and i am paying a lot of money on a A30 contract and now when they have to replace the handset they want to give me old phones Y5/Y6 2019 and that they dont have stock they are not even giving me an option to go and have this contract reviewed so that we reach an agreement now i feel i am being forced by Cell C to take a phone that i do not like I am a paying customer for them to be sending and giving me a run around i am just disgusted by their service and attitude in the emails they are sending me I am shocked and very angry. They are proving to be not even trying this also includes the fact that I cancelled router and still they deducted money in march Cell C is just proving not to care at all and causing me a lot of stress over wanting to replace my phone A30 for the choices they are giving me. Which arr not even close rk meeting the criteria of my phone and all of a sudden they are talking about premium which i dont understand i am fuming and not amused whith such ******* service.
