Terrible service!!

I logged a complaint on the 27 June 2023. I waited a few days until I eventually got a voucher that was sms'd to the wrong number. I called the call center and spoke to an agent who took my details and said she will call me back. She did after 10 minutes and said she sees the number is incorrect and will escalate it to the person who sent me the voucher. To date I haven't received any further communication from them or my voucher. I firstly got terrible food and now extremely bad services! My case number is: Burger King Case BK-77385-X6J9R2 CRM:***
