Bad to no service

I have given in my laptop 3 weeks ago for repairs, I had to pay a assessment fee of R295 and 1 and half weeks later was sent a quote of R635 which was paid. Last week Thursday I received an sms saying my unit was ready for collection but when I went to collect the unit I was told that the unit has not been repaired and there is another quote that needs to be sent out. Now one week later I still have not received the quote let alone my laptop. When discussing what was going on with the unit with someone from bolttech last week he advised me that the ssd is damaged and that the ssd is not a acer ssd, but this unit has never been open or repaired before and is still being paid for. How does a acer laptop now have acer parts
