No correspondence never helpful

Last year I was contacted by stupel and buurmen They are attorneys for standard bank and said that I am in arrears with my standard bank credit card I started paying an amount from march last year until April this year consistently and then I was told that LGR attorneys would be handling it so I paid them as a direct eft to their account I did this with both companies ,today I see an email from someone who works from LGR telling me that in July my file was recalled and closed and they are not dealing with me any longer , this I find absolutely shocking ,no one told me about this no one sent an email to inform me or to let me know ,I enquired about how much more do I have to pay as I have been paying and paid extra in June so surely I should have an indication as to how much I have left of paying ? So for the month of July and August I paid LGR directly this correspondence was not given to standard bank now I get an email from standard Bank saying I am in ARREARS this is so frustrating, I don't want to give my personal information over email as they have previously asked as I have read on standard banks page that they will never ask for personal information yet they asking me for it and I am so scared that it might be a phishing scheme please can someone from the standard bank credit card department give me clarity as to what is going on and if they can tell me how much more do I owe and most of ALL WHERE IS MY MONEY GOING TO IF LGR HAS CLOSED MY FILE ,your assistance is highly appreciated in this matter
