VODACOM OFFERS SERVICES THEY DONT HAVE

Many months ago, Vodacom advertised "Whatsapp Ticket". I purchased this and a few days later I contacted Vodacom to advise that the ticket was no longer working and all my airtime had disappeared. I was refunded with R29 and told not to use "Whatsapp Ticket" as Vodacom was 'working on the problem'. I would be advised via sms when "Whatsapp Ticket" would be available again. To this day the offer remains on their list yet one cannot make use of it. I have approached Vodacom stores on numerous occasions and called their customer services, but am repeatedly told "Our team leaders have not advised us of any new developments." When will Vodacom finally let their customers know what the problem is and how long will it take them to resolve the issue, or whether the problem will ever be sorted out? If the problem cannot be resolved, then Vodacom must remove "Whatsapp Ticket" from their list. Clearly Vodacom is copying other cellphone companies by offering the same service, but with the difference that Vodacom actually cannot provide the service. That way we'll know to make our purchases at other cellphone companies.
