Pathetic lack of any customer service from Vodacom

This is now the 3rd or 4th complaint I am lodging about the same matter at Vodacom and still absolutely no one is interested in assisting me with a simple query of itemized billing and refund that is owed to me due to incorrect billing. after just spending another 20 minutes on the phone with supposed “customer care” from m another country costing me international call rates , my call was once again transferred and then abruptly terminated by a lady who goes by the name of Phumzile. I am absolutely appalled at the manner in which Vodacom treats there customers. And I have been a customer for more than 20 years. My wish is that someone from any department there that can help me would contact me via my email address ********** and solve my concerns. I eagerly await the contact.
