Telkom jist cut all my lines.

I have been with telkom for over 10 years. They sent me a message my account is close to over my limit and i need to contact them. My debit order did go of vor over 5k and there statement shows i am up to date yet they switch my network of for all my phones all of them. I run a business and now it is grind to a halt. They say my account is sitting on 6.6 k it is the 7th of the month . I ask for a statement amd my account says i habe 0 rand balance on 30 /60/90 days and my next debit is just over 5k how does there system work. Instead of sending me a email or a call with the problem they just cut everything. This is the last time telkom lets me down. I am moving all my contracts. It is fryday and theu say the payment i made now 700rand will take 2 working days to load. So my business is standing for 4 days in total or more.
