Vbstein,
We do take your complaints seriously, can you please post in the after sales support link below with the invoice number(s) that relate to the 4 RMA(s) you are referring to?

Whilst I appreciate the comments you have made about Currys/PC World it would suggest you return item(s) to their store in person? SCAN also have a returns/technical reception where faulty goods can be returned/tested and replaced whilst you wait (stock permitting of course) however I would assume your returns were not brought into our store?
Regards
