Worst Vodashop to deal with

I would like to bring to attention the bad service from Vodacom and the cover up for the Vodashops which should be under the care of Vodacom.When there is a problem or a compliant about a store then clients must sort out the problems with the store and Vodacom does not worry about that.The question that i am asking is why give them the name and then they can do anything.I have had a problem with the consultant Devan who is now the Manager at the Westwood Mall Vodashop.This guy told me that my Samsung S4 Mini had a screen warranty if damaged.Now that this has happened were the screen cracked i take it into the Samsung Repair Centre i am told no warranty and Vodacom wants no dealings with the compliant.The person by the name of Mr Lee Roy Hull sends me an email and then when i reply he does not even care to resolve the problem.Customers must now be aware with dealing with The Vodashop Westwood Mall because all they are interested in is making a sale and forget the customers.I cannot even get hold of the owner of this store. how do you win with companys like this? VODACOM IS A VERY BAD COMPANY WHEN IT COME TO COMPLIANTS.
