Samsung microwave repair depot location

[notrub]

Samsung, great products very poor customer service.  This should be their motto.  I have a 3 month old microwave purchased from lazada.  It does not work properly.  Heats one time and then does not function.  Then it works again one or two times then not.  Domestic  light use.  I have been trying most of the day trying to get a response from Lazada and/or Samsung to help locate a repair depot.  I am 100 km north of Buriram and have thrown away the box so I would prefer taking it to a depot.  Any ideas or suggestion about where I can find such a repair service?  I have, in the past, located one just outside Korat but cannot find any reference to it now.  My friend has the same model with exactly the same problem but bought from home pro so he will just return his there.  Any ideas please?  Thanks.

Found the one in Korat using Google Map search.  Thanks

There is a Samsung service centre in Surin, which also covers Buriram.  Though, you being 100 km north of Buriram, the Korat one may be closer.
