Extremely poor customer service (i am really disgruntled)

I joined discovery last year December and my plan was effective from the 1st of January 2018, I am extremely disgruntled by the way discovery has dealt with my queries.

January 2018- I called requesting for my card to be sent: I was told that the card was already sent to my home address but when I explained that I didn't receive the card was told that they will log a call on the system to resend the card. February 2018- I called again following up: Was told the card was sent to my work address when I advise them that I didn't receive the card was told that a call will be logged again for the card to be sent to my work address.

3rd time I called Discovery was 7th of March 2018: All of a sudden was told that if you are on a smart plan you do not get a card (this is really disheartening because Discovery assumes that everyone has a smart phone "I think this is stupidity at it's best" basically they are assuming everyone has a smart phone "putting everyone under the same blanket") what really frustrates me is that the first and second time I was never told this(Even Fatimah Lampat hesitated a bit before telling me this, it seems like she was not 100% sure) this is really crazy.

I think Discovery did not think this through, how do you generalize like this, I mean some of us use laptops to access the web (they assume that everyone should have a smart cell phone and you should always carry your phone when visiting a doctor) what I stupid idea.

I am really frustrated, poor poor customer service
