Who called from +60 155372909?

I just got a call from this number just now. It has weird operator voice claiming she is from poslaju ( for the first time, i heard chinese slang operator from poslaju, weird isn’t it?? In my lifetime, i always hear to malay woman operator voice ). I have such a blur mind and I accidentally forwarded this call to a man ( i dont buy anything lol ). He ( might chinese.. bcs of his slang ) asked why this call is forwarded to him, and asked me if i bought something using poslaju courier.. we feel like dumbs. I think it might be a spam call but i dont know.
