NO BANK SMS'S FROM BANKS AFTER PORTING

I have ported to Vodacom from MTN hoping for the best experience, however after the port I have been on the phone none stop trying to get my bank sms's to come through. Vodacom told me I should go to the banks. I went to all 3 banks I bank with and they showed me logs of sms's sent and delivered to my number but for some reason I did not receive them on my phone. I know that this would have to do with routing, I contacted MTN they also push me back to Vodacom. WHAT MUST I DO TO GET MY BANKS SMS'S TO COME THROUGH??? I DID EXACTLY WHAT THEY TOLD ME, I WENT TO THE BANKS AND ALL IS FINE FROM THEIR SIDE. SO THE PROBLEM LIES WITH VODACOM AS MTN IS ALSO SAYING THEY DID EVERYTHING RIGHT FROM THEIR SIDE. I REALLY NEED THIS SORTED OUT AS MY LIFE IS ON HOLD , I CANNOT TRANSACT ON ALL MY BANKS DUE TO NOT RECEIVING OTP'S. IM STARTING TO REGTRET THIS PORTING TO VODACOM, IT SEEMS THE GRASS IS NOT ALWAYS GREENER ON THE OTHER SIDE. VODACOM BETTER FIX THIS AS AM NOW THEIR CLIENT, WHATS FUNNY IS THAT A FEW YEARS AGO WHEN I PORTED TO MTN FROM CELL C I DID NOT HAVE ANY OF THIS ISSUES. SO IT CLEARLY MEANS THAT THE PROBLEM IS WITH VODACOM. FIX THIS IMMEDIATELY!!!
