There are many grammatical errors There are many grammatical errors in the book. It doesn't mention a lot of exceptions. So the students have a lot of questions and it's really difficult for the teacher to handle all of them.

The magazines were a gift to my…daughter The magazines were a gift to my daughter. Now that she's a grown up it took me ages to cancel my 10 year-subscription, with threats of an 'incasso'bureau. Can you f**king believe that arrogance and distrust after 10 years of flawless payments ... Shame on you National Geographic.

Digital membership didnt work; no service Signed up for a paid digital membership: content was good, when I could read it. Every article I tried reading would hit me a paywall popup telling me to subscribe, despite the fact I am was subcribed, logged in, and paying. Sometimes they would go away after waiting a while, sometimes the payway would not go away. Customer service sucks. They don't even respond. Never responded to multiple emails requesting they cancle my membership and stop charging me.. Tired of having my mailbox filled up with stuff I cant read, I clicked unsubscribe. Nat geo site responds 'it may take 10 days' for the system to stop spamming me. 10 days? Hell even junk mail marketing from boner pill salemen will stop immediately when you hit that unsubscribe button.. Nat geo/disney, you suck

They'll harass you forever Be careful about getting a NG membership and magazine. They will harass you forever. I tried to cancel my father's membership when his Alzheimers progressed to a point where he could no longer read. Every other subscription promptly cancelled and refunded. Not NG, I had to let the whole subscription run out. And meanwhile they sent demand after demand for renewal. I politely asked at least a dozen times over 4 years for them to leave us alone. Now my Dad is DEAD and they are still sending renewal notices. They are heartless monsters.

Fire customer support people Just had the most ridiculous conversation with not 1 but 2 (supervisor) customer service people..... First from Philippines who COULD NOT UNDERTAND AND ANSWER BASIC QUESTIONS RE: no issues received for 3 months. Both she and supervisor (American who spoke English) could not listen or understand the problem. Each gave different info re: problem, then adding 3 more problems. Glad to find N G complaint site....seems I experienced same problems with customer service. Simple questions, rude etc etc etc....... ....will not renew current sub...
