Shocking Customer Service - Lisa Raleigh

I registered online with www.lisaraleigh.com to purchase a rebounder. The registration online was done on the 11th Nov at 07:06am , I then received a welcome email to confirm the account on the 11th Nov at 07:07am. I processed my order and made payment for R6798-00 on the same day.

Four hours later at 11:08am I received an email with the discount code of 15% which is valid for 48hrs. I immediately sent an email to marketing@lisaraleigh.com with no response.

I contacted the store on the 12th Nov at 08:30am and spoke to Vanessa who said she would send my query to accounts. Emails back and forth with proof of the time stamp for each email and they will not refund me due to there system error , they will also not cancel the order so that I can re-order using the discount code and they will also not refund me 15% of my purchase. What they do offer is a 10% discount on my next order which does not match the discount code received for 15% Lisa Raleigh I am shocked with the response received. This is not acceptable customer service. Rebounders are not cheap.

Please refund me the 15% as per below

5% Off with code Checkout5 (Spend R2500 and below) 10% off with code Checkout10 (Spend between R2500 - R5000) 15% off with code Checkout15 (Spend Above R5000)
