Vodapay

I bought a voucher on the Vodabucks App on 04 April and contacted Vodacom on the 5th of April via the whatsapp service. I then spoke with a consultant who indicated a call will be logged. I never received a sms notification for my call, so on the 6th of April I again used the whatsapp service and another consultant contacted me. He advised me i need to wait 3/5 days before i get an sms with the voucher. Once again i never received the sms nor confirmation of the call i logged. Then on the 11th of April I again went via the whatsapp service, this time the consultant was honest and advised me a call was never logged and that he will log a call for me. I received sms notification and on the 20th of April i just got a notification that the call has been closed. Today is the 28th i never received a call again from Vodacom and my funds has not been refunded.
