No feedback, very frustrated

My car has been in for a bumper repair for a full 3weeks and I am being sent from pillar to post by Discovery just for them to authorize a new bumper, Alberante BMW has been fixing the bumper and on completion of the repair on the 13/11/2015 they told me that the car failed quality inspection which will require a new bumper, so all Discovery needs to do is to authorize Alberante BMW to order a new bumper and now the lady handling my claim is either not responding to my emails or returning my calls which I find very frustrating and also very unprofessional <br> Matshepo told me 2days ago she is awaiting feedback from management and I'm still waiting for her to get back to me. Discovery is very much aware that the courtesy I'm driving should be returned to Avis on the 28 November. what I find so offensive and insulting in this whole thing is that Discovery are normally the first to debit their money from my account and I have never skipped a payment and with this treatment I feel less of value or a client to them.<br> <br> Alberante BMW is just awaiting they authorization so that they can order the new bumper and replace it, even management of Discovery does not respond to me emails.
