Extremely Disappointed

I purchased a Mecer Notebook in December 2019 - Took the laptop into the store on the 12 February 2020 as it was not powering on - received the laptop yesterday 18 March 2020 - not repaired as it apparently was liquid spillage damage and the quote was equivalent to purchasing a new device - which i will still dispute. The laptop came with a memory card which is now not in the device and the only justification is "Sorry it was not written on the job card that there was a memory card when it was booked in" - This is ridiculous - so if the person booking in the laptop did not make a note of it and it goes missing while in your possession then it is ok for me to suffer further losses. (I am not even mentioning the lethargic attitude of the staff who seem to not know anything about whats actually happening within the store)
