ADOBE RUINING MY CREDIT RECORD AND BACK ACCOUNT AND RELATIONSHIP

I added my banking details for one month trial on Adobe. There were documents I needed to save. I forgot to cancel the free trial and needless to say ADOBE didn't warn me. They then tried to trace payment from my account but there was no money because I wasn't working. Adobe have since been tracking my account DAILY AND CAUSING ME AN UNPAID AMOUNT OF R3-00 DAILY. There is no option to cancel the subscription. Unlike other companies who offer a client the opportunity to cancel, they don't have the option and keep ruining my bank account. I tried to put money in my account but then they didn't track it until the mone money was depleted. They have noe started to drain my account with R3-00 and R7-00 unpaid amounts. I have no choice because they clearly own my account. They will continue ruining it until Capitec closes it. Someone please help.
