Simple request to cancel device insurance

A simple request to cancel my device insurance was already submitted at the start of June and still, this request has not been fulfilled. I was billed again at the beginning of July for the insurance that should have been removed at the end of June, so now I will have to pay again with my next debit order on 1 August. I am utterly disgusted with the level of service I am receiving from Vodacom at this point in time. I have never ever had a complaint and also always paid my accounts in time, however it just feels that this simple request is too much for your staff to handle. nobody wants too take ownership and just sort out the matter. So disappointed in you guys really....
