I got a call *** at 13h43 For a phone application for SAMSUNG A35 5G. The device going for R389,then she added additional extras. I told her to cancel the contract application,but instead the agent told me she almost done with the application. The agent hung up the phone. The I received debit order verification sms and a contract on my email. I called both numbers *** and *** it states they are closed. But on the internet working hours 08h00 to 17h00. I want my contract application canceled .
