Deceased husband - struggling to transfer contracts to wife

My husband passed away in July 2020. He had 3x contracts in his name, one for his personal use, one for my personal use and the other one for internet. Went to our local Cell C shop on 06 August 2020 and asked to have all 3 contracts transferred to my name. Supp**** all necessary documents ie bank statements , Id etc. TWO months later, nothing happened except for case ref nr on 19 August. I am in business myself, need my phone for banking and one time pin from our networks on a daily basis and stay all by myself now so also need phone for my security systems. Our auditors who handle his estate are just waiting for phone contracts to be transferred to myself, because they need to close his bank accounts. Nothing can happen regarding his estate, I cannot get any of his pension fund, nothing, just because we still cannot close his accounts. Can somebody PLEASE PLEASE help me - so scared I might loose my number that I have been using for so many many years. Cannot believe that this take so long - everything needed was supply by myself,
