Pathetic service

I have a Defy oven and the glass on the door shattered. Tried to order a replacement from Defy Monteque Gardens. The lady at spares were extremely rude and told me if I dont have the product and part no they cannot assist. I took the matter up with the manager who got a lady Devere Thomas to assist and while she did a great job and eventually got the part it fell apart again. She send me all the details, I made a payment via EFT, send her the proof of payment and arranged with the couriers to collect. Next thing another lady Milnola Basson calls and says she will not give the part to the couriers as the payment must reflect on the bankstatement for 48 hours and she has not seen the proof of payment. I send to her but her email rejects and when I call her I hold on for 10 minutes then she states she cnt hear me and will call back which never happens!!! This is really pathetic service!!!
