Terrible Vodacom Customer Service

I called the Vodacom customer care line (135) on 19/09/2022 at 20h13 where the phone was answered by a male by the name of Thapelo. I was calling to enquire about the unusual data charger I was experiencing and needed clarity on what might have been wrong because I’m a loyal Vodacom customer for years. He then rudly told me that he was going to “put his head on a block and refund me” and that “he wasn’t going to go back and forth with a customer” -im paraphrasing but in between the chat he kept making snaaks remarks and sounds. I ended up telling him that he shouldn’t make me feel guilty for refunding me because I did feel that my data was depleting in an unusual way. There’s no way I could buy 2G and it finishes in +-an hour and then another 2G while that depletes in +-45 min while I’m only on WhatsApp and twitter. At the end of it all he said he doesn’t have to refund me and that he’ll rather log a claim and I’ll get a reference number for my call. This is all after I wanted proof , in writing, of my alleged data usage. He dropped the call on my ear and I still haven’t received a reference number. Can somebody please attend to this matter because I’m a paying customer and we have rights and appropriate channels that we can go through to ensure that this doesn’t happen again to myself and other customers. Please don’t ever think we South Africans don’t have a voice.
