MCDONALDS KEMPTON PARK

I ordered a medium big tasty meal on uber eats and i was told after waiting for almost an hour that it is out of stock. the manager from your Kempton Park branch had the audacity to rudely tell me its not their problem and that i should call uber eats. This is not the first time I'm receiving this kind of service from your Kempton Park branch. i choose to keep quiet but today I'm furious. the service is disgusting and mediocre at best. should i not get a reply as soon as possible i will definitely tell people on social media.
