Talk about bad service

I am highly disappointed with the service Vodacom gave me i have been their client for more than 2 years now .Last month they didnt debit my account and i paid them directly , they didnt not sent ans sms nor call to inform me that they may be having technical problems, not on they 25th of the very same month September they go and debit my account , they debit order was unpaid. causing me bank charges. I called in on the 28th to ask whats happening and will they kindly fix the problem '.The call center Agent directed me to their Account department.I called their Account department the following day 29th and they said they will fix the problem it takes 7 working days and an sms will be sent to show the matter has been resolved.Today the 10 th October I log in to check if the matter was resolved now i owe the R1800,This has affected me negatively because It shows me as a bad payer and i have paid them . while am stilling fighting the billing Issue now my data is gone. from having a full 4 Gig to 1 gig that i didnt use. I think its time i when shopping for another network provider.
