WAITING 2 MONTHS AND ASKED TO KEEP WAITING. HEADSET/EARPHONES FAULTY

My hubby ordered a headset/earphones from the vodabucks department. The headset does not work even when charged. I phoned them the day after on the 16th of OCTOBER. Gave them all his details and the problem with the product. I asked that they exchange it for a similar one in working condition. They said yes and amen. We then waited a few days with no communication from Vodacom. I phoned again and was promised a 72hr waiting period. This passed and I phoned again. The vodabucks team sound like they're either drinking or have all had recent strokes. Slurred speech and apparent "difficulty" understanding basic words. Hubby received a call and confirmed all the details with a man who again had slurred speech. We THEN hear nothing from Vodacom and I call AGAIN. This time apparently the delay was that they did not get hubbies details which is I swear to GOD IMPOSSIBLE SINCE I SPELLED EVERYTHING OUT, "A FOR ALPHA...ETC". I complained on X and Vodacom asked me to DM them. I did that on 03 DECEMBER. When reaching out again, apparently they are still waiting for feedback. SINCE YOU ARE AN ISP I NEED TO KNOW WHY THIS IS TAKING SO LONG? IT HAS BEEN 2 MONTHS. DO YOU SEND YOUR REQUESTS AND COMMUNICATION VIA PIDGEON? WHY DID HE RECEIVE A CALL PROMISING ANOTHER CALL AND NO ONE HAS PHONED US YET? WHY IS NO ONE EXPLAINING ANYTHING TO US? WHY DOES VODACOM SO CONVENIENTLY FORGET ABOUT THEIR CUSTOMERS AND WE HAVE TO BEG FOR A RESOLUTION?????
