Dont use iSMASHED!!!!!

I think my MacBook may have been ****** by this company (this is my current personal opinion based on the fact that: Their contact numbers are no longer working, and emails sent are all bouncing! My MacBook has been with them from February this year. I trusted their service before as they had fixed my laptop on a prior instance. A quotation for collection was emailed on the initial repair request and a pick up receipt was signed for as well. On the second instance, I emailed them to request assistance, my Laptop was picked up, but no invoice was sent and there was also no pick up documentation signed (I left the laptop with our reception). I have no actual proof of collection! I do however have a email trail with correspondence to them requesting updates about the repair with delayed responses, up until this point where the emails are bouncing and the contact numbers are not working.
