In response to the allegations, World Duty Free issued an apology on Twitter.
"We're grateful for comments shared on social media today regarding our VIP voucher scheme," the statement said. "We've investigated this straight away and identified an issue which we have corrected with immediate effect. Please accept our sincere apologies."
The company, which is based in Bern, Switzerland, did not respond to requests for a full explanation.
A Heathrow Airport spokesperson said: "We have been made aware of this offer which we find unacceptable. We are currently working with our commercial partner to understand how this happened and ensure it does not happen again."
The allegations surfaced on Weibo, when a part-time Chinese employee at the store at the airport's Terminal 2 known as @Renjiannaipao, published allegations on the social media platform.
