disabling my account with no reason

I have been a loyal customer for a long time, my account has been disable due to their system not picking up that my debit order is coming off my account. When checking my bank statement it shows that Afihost has taken the installment/payment however, I noticed that my account was disabled which was a fault on their side. This is unacceptable. They then proceeded to send me a link after I queried this issue and what amazed me was the fact that I had to re-submit my banking details again. This is an inconvenience. Why did they not pick up this issue? If I didn't query it would it have been ongoing and for how long? I have recommended this service provider to many of my family and friends in the past.

I am not happy as a committed payer and customer. I truly hope this never happens again or I will be forced to not be a customer of Afrihost any longer.
