Hi there! I understand that you're having trouble making purchases online, and I'm here to help you figure this out. Let's break this down a bit.

1. Card Type: Are you trying to use a debit or credit card for your purchases? Knowing this can help clarify potential restrictions.

2. Error Messages: Are you receiving any specific error messages when you try to make a purchase? If so, what do they say?

3. Account Status: Have you checked to see if there are any alerts on your L’bankalik account? Sometimes banks put a hold on online transactions for security reasons.

4. Card Details: It's important to ensure that your card information, such as the expiration date and billing address, is correct. Have you verified that they are up-to-date?

5. Internet Connection: Is your internet connection stable? Sometimes connectivity issues can lead to failed transactions as well.

Let's start with these points. Once I have more information, I can suggest the next steps.

Cart type

It looks like you might be referring to the type of card you have with L’bankalik. Generally, L’bankalik offers different types of cards, such as Mastercard debit cards, prepaid cards, and more. Here are a couple of options based on the available information:

1. Mastercard: This is a standard card type that allows you to make purchases online as well as in stores.
2. Prepaid Cards: These cards allow you to load money onto the card and then use it for purchases until that balance is depleted.

To help you further, please clarify if you’re using one of these cards, or if you have a specific type in mind. Is your card type supported for online purchases? Let me know so we can get this sorted out!
