Not taking responsibility/ Bad technical service

I am having issues with Vodacom since I ported in January. My issue is with not receiving sms's from my bank. OTP, notifications, etc. I have attempted on MANY occasions to get this resolved, and have been given every excuse available. I have even gone to a Vodacom shop to try different handsets.<br> <br> From my bank I have statements in writing claiming that everything from their side is configured correctly, and working as expected.<br> <br> I have tried to escalate this to 3 different supervisors that were not able to get this resolved - Ambani, Brandon & Gerhard. I have also tried to post this on the Facebook page, but all I'm getting is a \not our problem"answer.<br> <br> At least FNB did investigations from their side"
