Walgreens review: Customer service unapplied coupons and monies applied

I spent over $176.00 last nite and get home only to realize for whatever reason over $40 in coupons were not applied, nor did I recieve any of money in points I should've recieved and was also supposed to recieve a $15 mail in rebate. This is ridculous and not the first time it has happened. All coupons were already saved to my acct so there is zero reason y they shouldn't have been applied. Its just shameful. Im seriously ready to stop shopping here altogether.

Id appreciate this to be resolved quickly
