Terrible service

Absolutely terrible service! Brand new Samsung s10 plus .. had a camera default .. took it to mm all electronics and after explaining myself that the camera is blurry they booked it for service . Told me it takes 2 business days .. It actually took 4 business days. Fetched it and there is scratches on my fone .. the lady says .. technician said its the screen guard .. like hell it's not my fault.. I gave u a brand new fone ..I complained to another consultant and he was like no stock of these screen guards.. he can order and I can fetch.. I was like hell no! I dont live down the road .. it's a drive to get to you guys!.. the cheek to tell a frustrated client that!.. I told him to deliver it at my work latest Tuesday mid day . I really want to see if they keep to their word .. for a brand like Samsung to treat clients like they are just another number .. absolutely pathetic! .. I don't ever want to deal with this store
