Pensioners overcharged!

PicknPay kwa thema over exaggerates their prices. Kwa thema is an informal settlement majority of people earning some sort of income are pensioners. Im handicapped myself but when i left shoprite and checkers for their bad service and ridiculous prices to find some sort of relief maybe from PicknPay but i get smacked with more nonsense!? I need help please; oh... "happy human rights day."
