So my review for today is Belgravia ,they do gin and pre mixed gin products like gin and tonic and gin and dry lemon.i like my gin,it used to be Goudens but for the last few years I switched to Belgravia,I enjoy their pre mixed range,there's 3 or 4 of the 440ml cans in the fridge as we speak.so when my friends suggested a overnight fishing trip my luggage included a bottle of Belgravia Gin and a case of 660ml Belgravia Gin and dry lemon.we got to the spot,set up,and decided to have a drink before we cast,first bottle of dry lemon flat,second flat same with the 3rd,at this point I'm disappointed, I've paid money for this ,this never happened before,I ended up dumping the whole case and switched to savanna which a friend brought, here's were it gets interesting ,we got back this morning, had some rest,after I got up,while relaxing I thought I would reach out to Belgravia to share my experience, I sent a mesg through Facebook messenger and was told I can not be helped because I have no proof,which fair enough I understand but you on a leisure outing with the boys last thing on your mind is keep proof.customer care was no help,basically no proof no help,out of curtesy I informed them of my review on hello Peter,the funny thing is I get asked what proof will I be posting on hello Peter,when will I be posting the review and so on.so as much as I enjoy Belgravia beverages I guess it's time for brand changes because if a company can't look after it's customer's, the very same customer's that's buying the product and growing the business starts with customer service, no customer's equal no sales equal no profit equal no job.
