Sometimes, we need to add more credit than usual and make several payments in a row.
For security reasons and to protect our users' credit cards our payment providers defined a maximum number of successful payment attempts within a defined number of days. If you exceed this limit then your payment will get rejected. Unfortunately, this is beyond our control.
Depending on whether you are a new or an old user, this limit may vary.
If you have any problem, please click on the "Report a problem" button at the bottom of this page and we will happily assist you the best we can.
