XXXX of all, I am a LEGAL XXXX XXXX XXXX XXXX XXXX XXXX XXXX. I came here at the invitation of the XXXX Government and when I got in the USA the financial / credit system was new to me. I 've learned that I have to build a credit history and credit points and I have to prove that I am an educated planner and responsible credit card user which I did. XXXX of the XXXX credit cards I obtained was from Home Depot and because the credit line was small I could n't use it very much, and my credit score at that time was not enough to request an increase and I was advised to wait some time and then to request an increase. Mean time I builded my credit points, I worked hard to pay always on time and here I am with an Excellent credit score after a couple of years. I constantly checked on my online Home Depot Credit Card account to see if there is any line increase available for me but all of a sudden my account was closed. There was no notice, no letter, no message about the closure, I just discovered that from the Credit Bureau that is a mark with an account closure and I had no knowledge about it. There is no limit in their terms and conditions for not using a credit card before it is closed. I contacted the Client Care and the person could n't give me a time limit for not using a credit card with them and it seems arbitrary - they choose when to close an account or not. I was advised to re-apply but that means to hurt my credit score. Then I asked to submit a complaint and I got no ticket number. The Client Care representative told me : " There is no way to provide you with a tracking number. I can not give you anything such as an email or notice. Your complaint has been forwarded to a specialist ''. 
At this point I do n't know what 's their terms and conditions regarding the time I can have a credit card without using it and what is the status of my complaint.
