They called me last year and 3 times this year in July.
They claim to be a air conditioner service thats offering their services, they didnt say the name of their company tough.
"Air conditioner service" is kinda general. Thats like somene calling you and saying "hello im a car mechanic can i come over and fix your car?"
Judging by their phone number they seem to be near this adress 01/777 5600 Heinzelova 39, Zagreb.
That is on the other side of the town from me so it seems kinda strange that they would call me 3 times in such a short period when i told them i was not intrested the first time.
