VERY POOR SERVICE

I ordered 2 x Brilliant White teeth whitening kits in December 2020. I have received them but have a query. I sent the query via their website - no response, I have emailed them twice - no reply. I tried calling them on numerous occasions and "the subscriber is not available". I have spent alot of money in my opinion and cant believe this is the poor service I am getting. Wont use them again!
