Dissipointed customer

Was called by a sales person and they told me the product would cost me R30 extra per month on my existing contract when billed it was 120 more per month tried to have it reverses and it cost me 1 hour on the phone from one person to another and still was not resolved....but decide not to pay your account then you get blacklisted...The sad part is I've been with Vodafone for over 20 years and this is the second time I've been **** to by their sales people not to mention when you want to cancell an contract and it becomes a mission...I am done with Vodacom this company just wants your money ...
