Overcharge on Device After Cancellation & Unauthorized Debit Order AFTER

Overcharge on device even though the contract ran it's term and we cancelled contract.Cell should have only charged for the sim; but they charged for the device as well.This may often be overlooked by the customer and they coin million on this device overcharge. If for example my monthly charge is a total of R600 and the device is R300; do the math if you multiply this by a few 100 000 customers.Also after the contract was cancelled Cell C debited my account with a R100 - for what. This is why technically Cell C are INSOLVENT. The consumer council and the telecommunication ombudsman should look into Cell C's business practices .
