Pathetic service

On Good Friday I went to McDonalds fourways mall and made a purchase using the points I had on the app…at the time of making a purchase I had 7+ points and wanted to buy a big Mc Chicken/Beef…close to finishing the purchase the system kicked me out and I then approached the lady cashier who said to me it will take up to 24 hours to get my points back,mind you I was hungry…I ended up using my bank card….i went to enquire at Mc Donald Randpark Ridge and the lady said she is not able to assist…I sent numerous queries on the app …till now I am still waiting let alone a feedback or acknowledging of the query…this type of service annoys me honestly…:I have attached proof of the supposed purchase which shows 4000 points being deducted for a burger I never received….I hope this gets resolved now that it is on a public platform…and whoever is handing queries on the app needs to be investigated and dealt with cause the person is not doing ***ol
