Account blocked for no reason

Last year I asked TFG to reduce my credit limit or stop it from going up. Currently my store account is sitting at 50k, of which I never agreed to or informed of. I recently made a purchase with the account and discovered that the limit was very high and the increases were never stopped. I then went to the store and spoke to someone to assist and they called "head office" I was then asked security questions of which I answered trulyful and I was told by the store assistant that I had failed the security questions, how does someone who want to ***** or commit ***** reduce their limit?

What about my right as a consumer to reduce or stop the limit from growing? Especially now with the security bridge/leak of customers information someone should have a right to limit their credit or reduce.

I felt like my rights were infringed upon and violated.

They even do not send me statements anymore, what is happening to TFG group, is it turning into another Jet? My account as we speak has been blocked all because I asked for a credit limit to be lowered.
