Very bad Service

So pick n pay (east rand mall) runs their sticker promotions just to tell you at the end of it all we do not have stock. Then they take your name to let you know when they do have stock. They then phone you to come and collect and once you get there is once again nothing. Then they tell you they will deliver once they have stock and never do. Then they make more promises they dont achieve. Then phone you again to tell you you need to collect and the following day phone you again to tell you to not come collect its gone again. Wow. What service.
