Vodacom is really becoming the worst

My father has contracts with Vodacom for many years now because they used to be the best network provider however when I ordered the Samsung Galaxy S7 I called in to have the phone sent back I spoke to several advisors yet nobody cared to have it sent back. I'm so furious I spent all this time trying to just get assistance. Im so unhappy when I ordered the phone they told me I will receive a wireless charger nothing came with the phone okay when I called up for it the advisor didn't know what it was then I explained it to her then she said she doesn't see it when I requested to speak to the manager the manager could tell me my exact order meaning that they opened the account but guess what nobody verified the account nobody even cared to ask who I am they could have been speaking to a total stranger giving my father's personal information to a *********! Then I called back again nobody verified the account again! Out of 5 calls like 3 advisors didn't ask who I am I am so fed up with all the trouble I've gone through with Vodacom imagine someone else calls on my dad's account to order anything isn't Vodacom accounts secure.
