Poor service from Cell C regarding contract upgrade

Good day, i have been a cell c customer for many years, since under going debt review in 2019 i have been able to upgrade my 3 numbers with cell c without any problems, now with the latest upgrade i am informed that i cannot get an upgrade due to me being under debt review, i have not one but 3 active accounts. I am not asking for a new account or line to be added to my profile just for the number to be upgraded as i am currently paying for this contract without any problems. the inconvenience caused to suddenly be informed that cell c has changed terms and conditions without communicating with us as account holders is beyond ridiculous. please note that cell c is still prepared to continue to bill me for my monthly usage but not give me a device what is the difference. so cell c is also saying they dont care about their staff as this will lead to lots of contracts being cancelled and ultimately job losses. according to my debt review agent as long as my contract is being maintained and not in arrears and not under debt review there is no problem for an upgrade as it is just a continuation of the service currently received. Cell C your refusal to help us and not communicate with us is distasteful and unfair.
