Take what I'm about to post here with a grain of salt... but I think I know what is happening... this is just my speculation...

Due to the rapid expansion of cloud mining... including one of the biggest... we can speculate to who that is... they seem to be buying all the hardware mining capacity being released right now, especially current generation 28 - 20nm hashers.

I don't think Hashra is scamming anyone on purpose... I think this big cloud mining operation actually has an agreement to buy A LOT of the new Hashra units... so therefore the delay...

I think Hashra has decided that delaying the shipping is worth it to the end customer and they will compensate some way...

But again... I could be totally wrong and Hashra could be just scamming you but I don't think that is the case...
