Frustrated Online Query

I bought a 3 piece travel set in april. They had an offer buy 2 items the 2nd item will be R5, so I bought 2. When the item was delivered the 2nd set was incomplete... only 2 item were in that 3 piece set. I have been liasing with Foschini online from april to date.... not resolved. All I asked was for the complete set to be sent to me & the incompleted to be uplifted.
