30free gig

I upgrade my celphone on the 15 th of June 2017 ,and they gave me 10 gig for free just for 1 day because the next day normally I get my monthly data the gave my second 10 gig, andthe 16 August i get my third 10 gig. I only receive 20 gig instead off 30 gig, the other 10 gig was just for 1 day. Now if the branch personel told me to come back the 16th. Of June then I get my 30 gig, now this is not my mistake,, .
