Complain

I bought my laptop from Cash crusaders at twin city on the 16th of June 2022 I used it for a month then laptop just went off n I took it back on the 26th of August 2022 for a repair and they told me if the problem is mine I'll pay bt if the problem is with the laptop they will be responsible for it...until today I don't have my laptop with me..I went to the store several times they keep saying they still busy with it because the first IT guy didn't see the problem they took it to the second guy until this day am waiting for their call

I feel said because am a student am approaching my exams
