Why won't Barclaycard close my account?

I have took out a consolidation loan at a good rate to clear all my debts, I will now pay less to pay off my debts at a quicker rate. I had two credit cards, which are now paid off, one was with Sygma bank, which after three days of clearing the account they closed the account on my request.

But Barclaycard are unbelievable, after i paid it off, I rang them to cancel the account, they talked me into keeping the card, at a much lower rate, the next day, I rang them back and said no, i want to cancel, they then talked me into keeping the account, at 0% apr for six months (i'm so gullible, I said yes again)

I rang my local branch of Barclays, and arranged a 1-1 meeting, and explained I did not want to card anymore, they faxed Barclaycard, and it seemed to work. Barclaycard disappeared from my Barclays IPhone app, 2 days later it reappeared.

I rang Barclaycard, and told them, I did not want any offers, I wanted to close the account, they eventually said OK, and again it disappeared from my Barclays IPhone app. I thought its sorted.

Its come back on today

What else can i do?

Ignore it. (American Express is the same way.)

It could just be a problem with the ap.
Call Barclays and demand a letter stating that the account is closed.

You have a card which you owe nothing on. That is it, you just do not use it. Cut it in two and throw it away. You will continue receiving statements with nil balance.throw they away.
Nothing to get stressed about.

Cut up the card and throw it away. If they want to waste their money sending you monthly statements which say that you have spent nothing and owe nothing, that's their problem. Just shred them and put them in the recycling bin.
