Actually, our company is your custo

Actually, our company is your customer, fortunately not me, therefore I would suggest to keep the further communications via our HR.
However if direct communication can help to make my pants longer and to find the missing items for me and Frank (who got 2 jackets instead of 3, these 2 jackets were, despite him being taller than me, 2 sizes smaller than mine), his email is bphintco@bph.co.th

Unfortunately, I am afraid that Frank and myself are just the tip of the iceberg, I would be surprised that we are the only 2 “problem cases”. Whether that comes from lack of communication by our HR as you mention (reasons which I am actually also not too much interested in, I am more interested in results or current the lack thereof). Nevertheless I do know for a fact that it was not our HR staff who measured me twice: end of 2013 and a 2nd time early 2014; and I also know that my legs didn’t grow that much that fast.
