Promotional Discount Uber Offer From Ebucks

I took up the offer for the first ride with a discount of R200 from ebucks due to an emergency visit to hospital for my daughter's surgery and to my surprise the promotional code went through confirming it was my first ride with uber and after validating my account details to register for uber i was debited the full fare amount on my cheque account a few seconds later.

Why provide a promotional offer when you still charged me the full price that's not on and i feel that was misleading and goes against your terms and conditions.

Kindly refund my amount as soon as you can confirm the debit also view the attached evidence to confirm.

I need to be contacted on 073****204 or e-mailed on ********** with a solution to this predicament.
