Missing hard drive

I sent my Inspiron to have some keyboard keys repaired. It comes back with keys fixed but mouse pad broken. I send it back. They fixed mousepad but keys (the same ones) don’t work again. They work with USB keyboard. I send it back. It just got it back today. I power it. It says hard drive is missing”. I open it and indeed. It’s missing and they taped the connector. What to do now? Unbelievable!!!!
