After complaining twice mask wearing is still not taken seriously

Last week Sunday I wrote to Food*****s via their webpage to complain about their staff not adhering to mask wearing policies and I reported its to a manager in store noticing 2 staff with no mask on their faces and someone wearing the mask over the chin. They wrote back to me telling me it will be escalated to the regional team and the manager in store also promised to address it.

Guess what; today I am again in the store round about 2PM and again there are two people behind the butchery working with open meat and their masks are not covering their mouths or nose, only wearing it over the chin. The one person was the same person as last week.

They cannot be taking this seriously.
