Vodacom deleted my number

My name is Marius Tripa, I am Vodacom subscriber, and my cell no is: ***. My wife, Daniela Tripa, is also a Vodacom subscriber, and her cell no is: ***. She is currently overseas and had the number on SMS roaming since 16 July 2019. She is a prepaid customer and had this phone number for over 20 years. On the 14.11.2019, her number was deleted from the Vodacom network, without any warning, although it had airtime for R-103 in the account and it was on the network. I tried to call several times the Vodacom Customer Care Call Centre and they do not have an option to speak to a consultant, only self-help options. I eventually went to a Vodacom shop to complain and I was told that the number is no longer on their system and there is nothing they can do to give me back the number and the airtime. From that shop, the consultant also tried to call Vodacom Customer Care Call Centre and had the same difficulty that I had. She had to press a wrong option to eventually be able to get to a consultant. Over the phone I spoke to a consultant and then with a supervisor, and they both said blatantly that the number is gone, as well as the airtime, and there is nothing they can do to give it back to me. I do not believe that the number cannot be retrieved from the system and be given back to us, as well as the airtime. This is totally unacceptable as this phone number is linked to bank accounts for OTP’s, WhatsApp contacts, etc., and she is not coming back to South Africa in the next few months. I need this number to be reinstated IMMEDIATELY.
