Poor service at Vodacom call center

Vodacom is performing ********** stunts. I canceled my cellphone contract with them for 2 phones (combo deal), only to find out they did not cancel the contract on the other phone of which my brother was using. I called them to enquire about this. And I had asked them if they are aware that what they are doing is *****. Debiting an about from my account with me agreeing to it. I spoke to the cancellations department team leader Kabelo Molusi and he had assured me that they will do and investigation because I told the I want answer as to what transpired. Until today I’m still waiting on they call. Very poor service if you ask me.
