****Duplicate **** Hi Parveen, I have looked into this case. After a lengthy email discussion it transpired that you did not check the compatibility of the goods in advance, whilst the details were clearly stated on the advert. The items were advertised as Oral B COMPATIBLE replacement heads, with thorough detailed info on which models fitted which. We did refuse the return of the goods because you had opened them. The items were sealed for hygiene reasons and by opening them you made the items nonreturnable. Had the items been left sealed, we would have happily refunded you. The reason the issue arose was because compatibility wasn't checked. Thank you.
