Hey, you have problems.
You are carrying 27" of used TV from Far East all the way to Dar as LG TVs are not available in Dar and (when) you are asked to pay 200K you say you don't have.
First (Firstly), you rise (raise) all suspicious alarms by carrying a huge TV as accompanied baggage.
Second (Secondly), you are so stupid not to know (that you don't know) that TVs are subject to taxation, no matter what.
Next time use your common sense and know that we have LG TV dealers locally (local LG TV dealers) and they do not cost that much.
Who, in his right mind buys a used TV and bring (brings) it all the way from Singapore to Dar by air as accompanied baggage?
I am asking you, which airline? It seems the question is too hard to be answered(to answer).
Besides, you are talking about (a) TV but your picture shows an opened bag. Pathetic.
