Paying for unavailable Service

I cannot access my Itemised Billing online.<br> I have reported this problem (***) on April 24 and had no feedback from Vodacom.<br> I am paying for a service that is not available to me.<br> I am paying the monthly fee of R17.10 x 2 (phones) x 24 (months) = R820.80.<br> I am claiming refunding for the total Itemised Billing fee for the 24 month contract period for both phones + accumulated interest.<br> After reporting the matter to VODACOM on 18 May 2015 Itemised billing was made available on one number. Itemised billing on the other number is still not available.<br> Vodacom just ignores my complaints.
