Trying to cancel my late husbands contract!!!!

I have been contacting Vodacom of a weekly basis to cancel my late husbands contract and covert the number to a pay as you go. I eventually got someone to give me a settlement of R1731.90 and proof was sent to Vodacom and no one seems to know what is going on. Every time I call I get transferred back and forth between departments and I have just had it and that is also when the line is simply not cut on me. The fact that I have to deal with the loss of my husband is bad enough let alone chase Vodacom to convert a contract to a pay as you go when I paid a settlement to get the process completed. I want this contact I***-3 / *** cancelled with immediate effect and converted to a pay as you go on my name, all my info is on your system under *** and I want to be called and confirmed that this has been done on *** or *** or via email [Email Removed] or [Email Removed] <br> <br> Thank you
