Returning customer and account closed permanently

I was a customer of Mobicred for years, well that is what I thought. I used Mobicred for 1 successful purchase and paid them monthly, on time and successfully. This was few years back. This year, I wanted to use their service again because they service I got from them was professional. Now they tell me, my account was closed due to inactivity and I am unable to re-open it. Why don't they want to do business with returning customers? I asked where is the communication the client receives to inform them your account will be closed and you won't be able to re-open it if you don't use the service. They say no communication was given. Hahaha this is over my head and unbelievable This relates to the rating on HelloPeter of course.
