Unresolved Transfer of Ownership

I was working for a company that gave us cellphone allowance and the company requested employees to do transfer of ownership on the contracts. I submitted all the necessary documents in February in Malmesbury @ Vodacom and a few weeks later i received a call from one of the consultants to confirm that the transfer of ownership has been done. In May i find out that the transfer was never done, the contract is still under the company of which i dont work for anymore. It is still a mission to do the transfer still and not getting direct answers how to rectify this issue. Long story short, as of Friday morning 28 May 2021 my phone was hard locked- meaning that i cannot receive or make calls and I am self employed and obviously use my phone for business. I advised the consultant at the Vodacom store and she asked me to contact the call centre. I made contact with the call centre and i have been advised to call an 011 number whilst my phone is hard locked. Vodacom has been very pathethic in sorting this issue out
