Vodacom not helping in covid 19

Hi, I have had a very bad experience with Vodacom. I have tried since December to sort out my account as there was charges made that I did not know about which made my account go into arrears. But I have spoken to them to pay off the amount due. I was out of work since last year and my last decent salary was end oct 2019 and I did make payments still to Nov 2019. However I did speak to the accounts department in March to start paying end of March, but in the industry I am I do not get income with the covid 19 appademic. Clients has stopped their policies which ended me up having minus R21000.00 on my commissions. And I am not getting any income with the state our country is in. The President said that the companies must be lenient but low and behold, after spoken and emailed vodacom that I could not keep my arrangement for end of March they have handed me over to mbd. This is not legal is it? I also have a policy on the account to pay my account when I do not have income. Why did they not opt for that?
