Telkom disconnected my telkom mobile lines even after receiving their money

Debit order was taken off on the 30th April 2020 and both my lines have been disconnected. I have been trying to get ahold of telkom to get my mobile phone lines connected and to find out what is the reason for the disconnections but all operates are busy. This is unacceptable and when you call in it tells me that my bill is outstanding for over R9000 which is incorrect. Please can someone help me to get this sorted outas this is the only why we can work from home during this lockdown period. Can't work can't survive.
