Faulty goods sold online which stores do not hold stock yet they advertise on their weekly pamphlet

Bad service. Faulty goods sold online which stores do not have stock of, yet they advertise on their weekly pamphlet. Branches show under their stock as having available but When you phone or go to the store they are out of stock and didn't receive the goods. Staff at the stores are not helpful with goods bought online even with proof and after having consulted the online customer service several times. Game Also takes longer to deliver than other stores.
