Pathetic service Vodacom and Vodasure

On 14 January 2021 I phoned Vodacom to cancel my insurance on my phone as I became aware that they were charging me insurance even though I had a upgraded and received a new phone and had not requested insurance on the new phone. Time of call 09h52 - spoke to Thuto. I was told that the policy had been cancelled. I checked my account on 3 Feb and saw that the policy has NOT been cancelled. I called *** Vodasure at 13h01 and spoke to a Victoria.I was told that whilst Voda Sure had processed the cancellation, Vodacom had not She told me she would proceed to cancel the policy. When I asked why this had not been done previously I was fiven a rude response. When I asked for what guarantee do I have that this time it will happen, again I received an arrogant response. On both occasions I requested email confirmation of the cancelation. Previously I did not receive an email. On the 3rd I was told I would get one by close of business. It is now the 4th and still no email confirmation of cancelation. Pathetic service
