Opodo Fraud Website, Subscription Cancellation Restricted

I had an issue with my Opodo subscription, which I used in Dubai and then tried to cancel while I was in Istanbul. I cancelled the subscription last December, but despite this, I have been charged three more times, with a total of almost 600 Turkish lira taken from my account. Although I believed the subscription was cancelled, Opodo kept charging me. I tried to contact their customer service, but I could not reach anyone, and even the phone number they provided does not work. My subscription was created under the email address shbarakat.**@gmail.com, and I no longer wish to be charged or to keep any relationship with this service. I request a full refund for all subscription payments taken after the first month, and that my subscription be completely cancelled. I also want all my personal data to be removed from Opodo’s systems and written confirmation that no further charges will be made.
