Disgusting treatment during a tragic time

Dear Vodacom, I am completely disappointed in your service at this point. My cell number used to be on my moms name but about 2 years ago we went into Vodacom to do a change of ownership. Vodacom then gave me the paperwork and said my number was now on my name. My mom passed away a month ago and now they want to switch my phone off as it still reflects on her name. Isn't it enough that I'm grieving my mom and I need to use my cell phone and now you want to put my cell phone off due to your errors. Please fix your paperwork! *** this is my number. Many Thanks, Janelle
