Greedy CellC

For years I had two phone numbers on the same account. The last time that the contract was renewed this changed. Why? Since then I have had problems with affording my monthly bill through the effects of Covid to my income ... Now I see that they charged me money for something that was not my intention. I was never charged that fee with my other account. Currently my other account is due to expire on 26 June 2021. How come has CellC Become so greedy? They never gave me any relief from having a reduced salary over lockdown. I would like if at all possible for Cell C to look at their fee structure and see why they are losing clients.
