Discovery forcing me to pay excess fees twice

My phone fell, the screen cracked & the flap fell off. It was reported but forgot to mention the flap , While it was in for repairs i remembered that i omitted to inform them of the flap (the part on the side of the phone that closes the charging part) Wenzile Ndimande at Discovery advised that I speak directly to the service provider and I phoned spoke to Princess Stainbank who transferred me to the technical dept and I was promised that the flap will be replaced and an updated quote will be sent to Discovery. I then sent an email to Discovery (Wezile ) to inform her of the developments and that she should not process the claim without receipt of the new quote from the service provider to which she responded, \That should not be a problem
