Lack of service from Cell C Legal

My husband has passed away on the 24th June 2018, our cellphone contracts were in his name. We are self employed thus all our correspondence reflects these number. I contacted cell c on numerous occasions to find out the process so that I can change ownership of these contracts. I received a message on the 9th of July stating a cancellation request, I did not cancel it and my husband was not around to do it either. The last payment was rejected by the bank as my husbands bank account was frozen. I contacted Cell C saying that I will settle the account & need my numbers back. I have been pushed from pillar to post with no avail. There is so much of admin that needs to be completed when winding up his estate but Cell C has been the most difficult by far. I NEED my numbers back. I have been told to speak to the Cell C legal department but can never get ahold of anyone. I am so disgusted by the level of service I have received this far.
