Seriously Meg your day??

I have done the meg your day a couple of times and everytime i don't check the data - but my data has gone really really quick the last month since I have done the meg your day

So today I did the Instagram meg your day and I check my data - the data is coming from my normal data not the meg your day data???

Is that not false advertising???

I still have 1g meg your day data but my data is almost depleted

I am on the Instagram app so how can you get his wrong??
