BIS service still being charged after 2 years

I have just discovered, after scrutinising my Vodacom statements that I am being charged R59 per month for a Blackberry BIS service 2 years after getting an Apple iPhone from Vodacom.<br> 3 other contracts on my account - all moved to other phones are also being charged the BIS service - after 6 and 3 months!<br> That's R236 per month<br> . I write to urge everyone to check their statements and invoices and to urge VC to put some simple software in place to avoid this.<br> I trust VC will do the right thing and reimburse me immediately.<br>
