Horrible service from Vodacom !!!!

Dear Vodacom I am utterly disgusted with your service! My father passed away and we app**** for a transfer of ownership as well as to change the debit order details. Your company and Vodashop in Witbank Mall , cancelled all our contracts, send me a R36000 bill and left my mother which is 71 years old for 1 month now with no way of communication! Also our business celphone was blocked and cancelled and for 1 month now only empty promises of fixing it. This is unacceptable!!!! Your company has cost us hundreds of thousands of rands losses!!! All this said our accounts has never been paid late! How do you keep on doing business??? I expect a prompt response from you asap or this will be take further!
