Terrible MTN Sim swap process

I'm very angry and disappointed with the MTN Sim Swap process of this network. On the 24 June 2020,I lost my phone and I then immediately informed the Network with this and I believe automatically my phone was blacklisted and along with my numbers,I then bought a new sim card on the 25 June 2020 to do a sim swap as I have been using my old number for more 16 yrs.I then dialled 135 to do sim swap,I was asked few questions in line with the process and I was told that the given answers were not accurate and therefore the sim swap process was unsuccessful. Furthermore,I was told that I can also dial X135# I will be send an questionnaire. I waited and waited I then decide to call 135 again,after answering those questions,I was again told that I have answered those questions inaccurate and the process was unsuccessful and I again dialled x135# which until today I have never received this sim swap questionnaire. Now I'm fuming and very disappointed based on the following aspects: - I have been using this number (072 *** ***4) ever since I bought my first phone/SIM card from Vodacom and because of questions and unreliable MTN service of not send me a questionnaire I'm going to lose this essential number ,From my side I believe I have done wat was required but I was not helped. - Do these guys of MTN understand the importance of my old number,this number is linked to my banking particular,as we speak I,m also waiting for my COVID 19 results,and results needs to be send via SMS linked to my number,my MTN Zakhele Futhi shares profile is linked to these numbers, my on-line profiles are linked to this cellphone number that I have been using for more than a decade.

Can I please be assisted with sim swap (if possible) coz I desperately needed my old cellphone numbers back,and what puzzle me is that such a Network has no other alternative mean to do this,is there no other alternative means ? I'm worried that my number can be given to someone else and furthermore I might be missing some important calls and sms

Please help
