Was charged 990 instead of 600 for four items at ccd cunningham road... When i insisted on bill one mr. Adil hesitated...
Then i was give a hand written bill i have that bill with me... I'm very disappointed... It's very bad... If i don't get a proper reply... I would upload the bill on social mediai would i go to consumer court with this... Because i didn't get a computerised bill
