Hi Armit,
Thank you for reaching out and sorry for the confusion. We are BoldGrid Themes and our product is Total Upkeep backups and migrations. Our subscription is billed on a yearly basis. There is another company called Bold Themes that we hold no association with and that might be the source of the misunderstanding. If you can link us to the URL where you saw this offer we can confirm if it is ours or not.
I hope this helps to clarify. Please let us know if we can answer anything else for you.
