BROO

Yall this is so ridiculous
So I've got these two ps controllers for a year or so, and they keep acting up (buttons not working, controller drift etc) so I finally convince my dad to get them fixed today and SOMEHOW exactly today, right after I test them out to see what I should write down for dad (what's wrong with them etc) they suddenly start working like they're brand new, even tho they haven't been working for MONTHS, and no I haven't dropped them, hit them, or anything and so it results in the technician guy calling me and telling me that there's nothing wrong with them, wtf do I do?? And how did it even happen bro
