Poor service and misleading advertising !!

I can believe that Vodacom is still around . It is one of the companies with the worst customer experience in my life . I wonder what there rating would be if Synovate would phone there clients . They are very quick to let you know that your debit order has been reversed and disconnect your service . But do n upgrade and they promise that one of there friendly sales agents will call you !! And then they don,t even call , but just get an SMS to inform you that there is no stock . I have to phone in to find out what is going on , and there is never a supervisor or manager available , ARE THEY ALSO OUT OF STOCK ?????? HOW CAN YOU ADVERTISE A PRODUCT AND YOU KNOW THERE IS NO STOCK AVAILABLE !!! I think its time that we demand better service for what we pay !!
