No voucher sent to me

On 21 April 2015 Woolworths customer care agent CELESTIA WILLIAMS promised me a R100 voucher because my cranberry juice box broke and messed all over my desk. I have emailed back on Thu, Apr 23, 2015 at 9:24 AM, Mon, Apr 27, 2015 at 1:03 PM and Wed, Apr 29, 2015 at 9:01 AM only to hear absolutely nothing back. What is going on Woolworths? I know that you have my correct email address and phone number cause you confirmed them with me in the email. I'm losing my faith in you.
