Bad service, overcharging and cannot return goods

rosebank store 7 april 2026. asked for a gimble for i phone , checked price and decided to buy . then they took my phone and before said my screen and camera protector need to be changed and started doing this before i had time to ask how much Charged 799 for screen and 499 for camera protector, i asked why so much and they said because of war and they have a guarantee. ******* , these probably cost R400 max, Bully tactics. i bough a selfie stich chaged R2200, at macro R800, Light for zoom calls charged ocer R1000 should be R400 max, then when came to pay added on another item tried to chage total R10,500, then reduced to R8600, this is about R3000 more than it should be. no detailed receipt. i took items back next day and complained . told they could not reverse purchase and the manager would call me, would not give me their bane or number , still waiting for a call. disgusting bully forced selling tactics. they said if i had a problem i could always come back. id di and got pushed away .... never use them, they are sharks. surely I have a right to return unopened products next day - even if not the phone screen protector
