Account suspended while there's an active debit order

Every month same time my account gets suspended, while there's an active debit order that runs every month. This has been happening since March. When I call the call center I've been told I need to make an additional payment...why do I need to make a additional payment when there's an active debit order??? Because I need my phone, I end up making those payments. Again this month, I call in May cause my account is suspended, i was asked to make a payment of r135, I paid R150 on the 20th, debit order when off for r500 on the 25th. Today I get an sms that my account is suspended ***??? I put through a request for an agen to call me, eventually when they do call you the line is dead..no one speaks??? I am over the this bullshyt. I want to cancel everything I have with you. You making more money out of me than anything else. Also, why would the account be suspended or j have reached my bundle when I have wifi and work and at home??? Does it even make freaking sense??
