Touch bar problems intermittently after I spilled tea on the Keybord.

Hi,

I accidentally spilled tea on my Macbook keyboard. I ran to the third party service station and got the whole thing cleaned with isopropyl. It ran fine for a few days thereafter but then the touch bar started flickering and registering touches randomly. I've tried resetting the PRAM ram and SMC without luck.

I would be thankful if someone can guide me about what to do now. I am just a student and this laptop was given by the company. It would be really difficult to afford an replacement for me.
