Why does square double charge my clients card when online booking for services?

[BeccaH]

I have a booking site that collaborates with square to receive payments from clients however, every time a client attempts to pay a 50% deposit (which I require for services) it double charges them the remaining 50% fee. For example, if my service fee is $60 I require a 50% payment to secure the appointment of $30. The other remaining $30 would be charged later but square automatically double charges their bank. Can anyone help with this?

Hmm, that shouldn't be happening. For your issue, It's best to reach out to our CS Team directly to figure out what's going on.
