Ghent Entertainment Unit for TVs up to 65"

Waited a month for it to come, was supposed to come on the 6th Jan, got an email on 5th saying it wouldn’t come till the 20th so I had already cancelled the handyman putting it up. Got a text on 7th Jan saying it was coming 8th Jan, it came and the handyman luckily had a cancellation so came the same day. He built the units and there was a crucial peice missing- the bit what goes onto the wall to hang the units on. Neither of them were in the boxes for the upper or lower unit. Instructions were really hard also even for someone who does flat packs for a living. Not happy
