poor service, feedback

i have a billing query since the 26 october yet to received any form of feedback, i was told it will take 48 hours. i did an upgrade in september and paid in store for the upgrade bill shows there was a migration fee which i was never told about 3 call centre agents advised that it was an error, i also have a fee for R349 for additional data of which i never took. Well over a week still no help, absolutely frustrated. Today the agent tells me that many customers are having these types of issues that is down right poor service. i see the bill for the end of november and the billing is also incorrect so it appears that this is issues will be a reoccurring one. extremely disappointed with the service i shouldn't feel like i have to fight to have my money returned to me.
