Super bad customer service. Don't shop online

H&m has the worst customer service I have ever experienced. I will never buy clothes here again. Here is my story:

On August 17, 2015 I added 5 items for $56 in my basket. Whenever I checked out, I got my card declined. I changed my card 4 times, including a debit card that I had over $1000 in the account, so enough for the check out. All were declined with the same error " the information you enentered was incorrect... "

I called the card companies. They said they already open signal for h&m, if there was problems, it should have been from h&m, that h&m didn't get their signal back to process my order.

I called h&m, the representative insisted that I couldn't check out because of my cards. I asked to talk to a technical person to help me solve the issue. He said no one can help me because it it not H&M IT system get problem.
--I asked: "do you have enough knowledge about IT to tell me that this error is not from your system".
--He replied "Are you mocking me?"
--I said "No, I am serious. Are you an IT guy or a customer representative to help customer with regular questions?"
--He said "our system is fine. I have handled 4 transactions this morning and no one got issue"
--"Then tell me why my cards didn't go through."
--" I can't tell you why."
--" So transfer me to someone can"
--" no one can. Our system is working fine. You go check your cards at a store. "
--"let me tell you, even if you don't get problems with any transactions this morning doesn't mean nothing wrong with my account. And even if I am the 1st one to report the problem, you should help me.to report it to the higher level or to the technical team"
-- " Anything else I can help?"
--" you haven't helped anything "


Anyway I asked for my husband help. We used his card to check out at a Walmart store half an hour before we place the exact order under his account and by his cards at the same day. Hah, again 4 different cards were declined.
We called h&m. The representative said she doesn't think that the system was in problems. She thinks because I tried to check out so many times?! Alright, then i asked how can I buy things on h&m now. She said, go to the store. Hah, if stores have things I want, I didn't need to go online. After a long discussion and the representative kept saying no one can help, I asked her to transfer me.to her manager. She transferred me to her manger, Roy.

--After hearing what I have encountered, Roy said: "there is nothing wrong with our system. If you want, try back in a couple day, or go to a store near by".
--I said "storenear by doesn't carry the items, can you ship things on m basket to the store?"
--He replied "no, we can't do anything".
--I was mad " so I just want to buy things from you and I report that none of my cards, my husband's, and recently we just tried our mom's card and you are saying that you are not going to help me to figure out why the problem occurred?"
-- He said " yes, you are correct".
-- I said " so what are you good for?".
He hung up he phone.

Not only 1 person, but the whole h&m team were rude. They are talked to customers as we are begging things from them. It is not the way business should be treating customers, at least in the US.

I never want to purchase things in h&m any more.

This business doesn't have conduct. People who read my story, please consider if you want things from h&m.

I am waiting to see h&m vanished out from the market
