Incorrect billing on upgrade and snow ball of problems thereafter

<p>On the 18th Dec 2016 did upgade online - got e-mail to confirm all in oder on 18th Dec @ 18h38 and will be contacted within 72 hrs. Did not hear from Vodacom. Phoned in Jan 2017 to follow up as no contact had been made - Told that upgrade was cxl due to "invalid configuration" on 18th of Dec at 19h15 and no communication made to me . Told reason was that address did not match - delivery address diff to home add - delivery add was diff due to no one home and delivery requested to work. Then got upgrade delivered to work - device delivered but NO sim card - Was then billed R 1134.60 for a FREE upgrade as per online . Then tried to do sim swap and told that account in arrears after being notified that was going to be credited for R1134.60 . Appauling service received and no one care's - perhaps time to look at alternative service provider ?</p>
