BioTech USA ISO Whey Zero 2.27kg,Maximum Purity Whey Protein Powder with Zero Lactose,Gluten Free, No Added Sugar (Vanilla)

I’ve bought three tubs and the third tub tastes like soap/ very old protein powder. I tried speaking the Biotech USA and they refused to provide me with a new tub. Personally won’t be using this brand just because of bad customer service. Unfortunately will have to finish my tub as £45 is not cheap. The previous two have been fine and stopped upsetting my stomach.
