Horrible experience with miway

My experience with miway has been pathetic. I am a loyal customer for the last few years. Not a single claim. They double debited me for the month of August , dint get my consent to take my own money and they have left me with 0 balance. I have been on long calls and sent several emails..but the only response I get is that I will get back my money...but still no trace of my money. This is a horrible experience. What's rights do you have to debit my account without my consent..and it's a month on month basis..it's not even a contract or anything.i am tired of fighting for my own money and for sure not going to stay with you any longer
