my partner has ordered phytoseiulus from this company on my behalf 5 times in the last year. on 2 occassions the tubes have arrived and been empty. what the hell is going on ? it seems theres a total lack of quality control in this company, someone should be checking what they are sending out, twenty quid for a tube of wheat dust, im so angry about this and will never buy anything from this company again. oh and dont bother with emailing to complain, they dont bother to reply, you have to ring to get some sort of answer or excuse, yes you will get a refund or they send you more but you then get them 2 weeks after you first ordered.
