Written talaaq

Me and my husband were newly weds. Due to pressure and anxiety building up between both our families, my husband was made to write talaq thrice on a paper and this was then sent to me through his brother. My husband did not have the intention to divorce me thrice nor was he aware of writing this thrice would do. We both are now willing to reconcile, and I am still in my iddah period. Can you please advice and guide us as to how we can go back to living as husband and wife.
