Counterfeit shaving blades sold by Philips approved centre

It is with sadness I need to give a bad review about Philips as it is traditionally known as a reputable supplier. I went to the Eurostore in Woodmead to purchase SH50 shaving blades. The packaging looked suspiciously cheap ie non-Philips-like. When I questioned if they are OEM, I was assured 'yes, Philips changed their packaging'. The blades do not shave properly and after searching the www, I found out these are 3rd party chinese blades. I'm disgusted with the dishonesty from a Philips approved centre. I've been trying to report this problem to Philips directly but there's no *** to be found, only automatic 'bots' which require me to answer non-relevant questions.
