Line suspended and I am sitting without a phone

I paid an outstanding amount last week Friday the 14th of August 2015 which was a direct cash deposit at ABSA into Telkoms account and they suspended my account yesterday afternoon on the 18/08/2015 and I have had nothing but bad service from them in the less than 2 months since I have been with them .. They did not notify me on time that my debit order did not go through last month and now I am sitting without a cellphone .... I use my phone for work purposes and they just keep telling me that I have to wait 72hours for the line to be unsuspended and I cannot afford that .... they just dont care and I just want nothing to do with Telkom .
