Change of ownership NIGHTMARE!!!

Not sure which is more traumatic, dealing with the loss of a loved on or trying to change ownership with Vodacom. I called on 7 January and was given the procedure to follow inclusive of documents to be provided to change the owernship of a data contract. Documents and letter duly emailed on 10 January, followed up on 20 January to which I lost an hour of my life either being on hold or being pushed from one department to the other. Tried again on 21st January and spoke to legal which I was advised to do, they couldn't help, I was put through to customer service who legal should help. Spoke a manager who assured me accounts were the correct department, yip you guessed it...they can't help me either. I tried our local Vodacom branch who advised there are more forms to complete. My 90 year Gran lives 400km away from me and I can't just get forms completed which I why I went through the whole process on 7 January when I was with her. I can't fathom how nobody in Vodacom can help when I have a reference for my first call and a reference for the documents I emailed. Its easier just to cancel than have to deal with this nightmare!!!
