I recently bought a Phillips sonic toothbrush and registered it and was supposed to get a 20% discount voucher which I did get but it never worked so Phillips told me to buy toothbrush heads and that they would reimburse me the 20% it took only four weeks for Phillip to send me the toothbrush heads that I had bought and they had my money for those four weeks and up to this point I still have not gotten my 20% back I would advise people to try to shop elsewhere because Phillips customer service is not very good I am very unhappy with it
