On 4th December I made an order in kfc app at KFC - MADURAI ( anna nagar branch), but it wasn't updated in app, then i called customer support they didnt pick up my phone till evening, then at 9th call an executive attended my call and asked my querry i explained him and then he told i will get a call back but i didnt get any call back for 2 days so i again repeated this process for one week no one is picking up my call, i need my refund back asap. very bad customer support is run by KFC.
