PAY BY CREDIT CARD: In order to pay by credit card, you must first make sure that you use a credit card that can be used to pay online, has at least 3 months until the expiration date and the limit is more than the membership plan fee you have selected. If your credit card is not available for internet use, you can try to change it from your bank's online system or allow its usage on internet by contacting your bank's customer services. Enter your card number (16 digits), the expiration date of your card (in MM / YY format), the name of the card holder (as written on the card) and the CVC information on the back of your card (as 3 digits), and click the PAYMENT button. Your payment transactions are made through contracted payment institutions that are authorized and have the necessary security certificates and no information about your card is kept in Teksgo. Unless you cancel your membership, your membership will automatically renew (monthly / yearly) on your last preferred payment plan (you can cancel your membership at any time and your membership will not be renewed from the next term, but your membership will continue until the end of the term you are in). Therefore, in order for your renewals to be carried out without any interruption in order to keep the services you receive from Teksgo without interruption, in case of a change (for example, when the expiry date is approaching or the card is canceled, etc.) in your card information (stored by the authorized payment institution, not stored in Teksgo), it is important that you update this information (enter new information on the payment panel, which you can access from the membership information on your Teksgo Profile page) sufficiently in advance.
