No more excuses Vodacom!

My son's phone is under warranty. It broke during lockdown level 4. We handed it in. It was sent to Nelspruit for repairs. It came back still broken. No spares available. I handed it in at another branch in Middelburg mall on the 27th May, I was told it would take 2 weeks to send the phone from Middelburg to Witbank. I said go ahead because I'm not standing in a queue for hours for a technician to help. This is the 2nd time we have sent in his Sony Xperia XA1 Ultra. The first time we sent his phone in 2019 for repairs my son said he received a 2nd hand phone back from Vodacom because his first phone had no scratches and a cover on. What I cannot understand is WHY am I STILL PAYING for a NEW phone and getting a SECOND HAND phone. Is this what my WARRANTY covers? WHY the stalling tactic? Or is Vodacom hoping December comes first when my contract ends so that they do not have to HONOUR their contract? Why can't vodacom just give a NEW replacement phone? My son cannot do his homework because he hasn't had a phone for a month now!
