No one at Vodacom is willing to assist

I requested a reversal on my iPhone 8 on the 9th of January. I was told the couriers would collect it within 7-14 working days as it was done online. Since then I call almost everyday to have them tell me the same thing over and over; that the phone will be collected soon. It’s been a month and still nothing. Very disappointing. Pathetic from Vodacom. Clearly they don’t know what customer service means. I want a new phone or my money back. I’ve had it with you people. FIX IT.
