Vodacom has no customer service

Since 18 April 2018, I have tried to resolve a deceased estate with Vodacom. Emailed all to Legal department, No feedback from them, despite numerous emails. Reverted to FB page. Vodacom undertook to escalate and resolve. to no avail. More emails, to no avail, All I receive is please phone ********** . Phoned them this morning, only to be met by the most rudest arrogant agent called Monique, who referred me to Legal. No cannot give me a number, I need to email. What is it that you dont understand??????????? I have mailed them over 10 times since 18 April 2018 and still I dont have the courtesy of a reply to finalise this matter. Really Vodacom. is this how you operate professionally?????????????????????????????????????
