Horrible Service - no accountability

My name is Siya Mhlongo ***) - on the 20th i purchased a Ninjago toy at the Toys R us (***), the packet i bought in store had some silo tape and i asked the lady if everything was complete inside and she said yes - when i go home 4 of the 25 pcs were missing - when i called the store the "manager" said i must call the Lego company, to which i indicated that the packed had evidence of repackaging with the silo tape - i feel like these guys honestly do not want to take any accountability, the least they could have done was to recheck this before silo taping it and putting it back on the shelf - this was literally the last package on the shelf and im really disappointed at the approach your staff had in dealing with this issue
