vodacom ************* and unrealiable

I logged a complaint about a substantial data bill received two months in a row.<br> I was told it was my fault and I had to pay. So I did. I also migrated my contract because it was due for upgrade to a top up contract on a 2gig top up for R99pm and I signed a migration form accordingly effective 01/04. <br> I get a bill today for R2100 even though I'm on a top up contract. I'm disgusted by vodacom now outright defying my wishes and *****ing my money! I tried their contact centre. I was transferred to account enquiries. I held for 10 minutes, was asked to enter my cellphone number and then got cut off. I shouldn't have to be the one fighting for a bill I don't owe!! Contract cellphone number ***
