Upgrade rejection after 7 years with Cell c

I have been having 2 contracts with Cell c since 2014 and have been paying without fail. due to loss of income i had to go for debt review but the cellc contracts were not included in the Debt counselling because the debt counsellor advised that this are not credit agreements but service agreements. my contract is up for an upgrade but they refuse to upgrade the contract because i am under debt review. i feel discriminated against just because i took a bold step to fix my financial issues. they don't care and i was not even looking to upgrade with i contract that ill pay more on it was going to be the same amount i am paying now.
