PATHETIC, RUDE SERVICE

I did a upgrade on 10/02/2021 for an iPhone 11. Vodacom sent me a FAULTY phone. Phoned them to arrange a return. The lady helping me with the return said I must phone as soon as they have collected the phone so that I can cancel the upgrade and do a new upgrade. Fast forward to 08/03/2021 - phone was collected by Ram Couriers. I phone Vodacom to inform them that the phone has been collected. They put me through to the upgrades department. No answer. On 09/03/2021 I try to phone again. After a few tried a lady named Phiwo answers and tells me that I can ONLY upgrade on 01/04/2021. I ask her if I'll be paying for a phone then that I don't have. Her reply, "YES". I ask her how can I pay for a phone that I don't have after VODACOM sent me a faulty phone, she replies "it's how it is". After I throw a tantrum, she tells me that I'll be credited for the device. I ask to speak to Phiwo's manager/supervisor and she puts me through to the UPGRADE department after refusing to email me that I will be credited. WOW Vodacom!!!! Not only do you have rude and *********** staff, you also treat a 10 year customer with no respect - seeing that I received a faulty phone. If this is what Vodacom thinks about my business and money, I will definitely take it somewhere else! Phiwo (who didn't want to give me her surname), if it weren't for me having a contract with Vodacom, YOU won't have a job!!!! I dare Vodacom to pull the voice recording and listen just HOW *********** Phiwo is!!!!
