Useless Services Provider

I would not even rate Vodacom a star! My husband passed away in December and our Vodacom Contract is in his name. After notifying Vodacom about my husband death, a few hours later Vodacom went and blocked our numbers. It has now been almost 2 months and I am not getting any assistance. Vodacom Estate Department came back saying I owe then R3k. I paid our account up until January. After requesting invoices the department advise they can not assist with invoices, I need to Call the Call centre. I called the Call Centre and was advised I need to use the Tobi Whatsapp. After requesting invoices from the Tobi App, Tobi first wants to issue a OTP but my number is block so I am not receiving anything?? I decided I want to make payment but my number is blocked and I can not make any EFT Payment. Today I receive a statement and now I owe R6k. Vodacom charged me R3500 and I do not know for what. I have been asking for assistance from the Estate Department, Call Centre & Branch and nobody is helping me. This is a difficult time for me and Vodacom is just adding more stress to everything!!! This is honestly a useless services provider.
