Locked phones but upto date contract

I have been trying to call their call centre regarding my contract. I only skipped one month due to Covid-19 and I was owing R3170 they deducted R1589.07(29 May and 20 May) twice of which I believe it was to cover the outstanding balance of my contract. But now my phones are locked and I cannot get help whether from their call centre, website or app. When I try to log a call or get a hold of their agents the phone keeps ringing I've spent over R60 and the phone is never picked up. All I want is my contract to be updated and my phones unlocked since I have paid my balance
