Samsung — Order [protected] delayed by 17 days

I have ordered mobile from samsung eshop on 2nd feb 2023. Expecting it on 20feb as per booking. They delivered mobile cover on 17feb. On 18th Feb they send an email saying mobile order will be delivered on 7th Mar delay of 17 days!! They are not cancelling order as they are saying its partially delivered. They are cheating by sending delay email post one day of delivering partial order. No cancellation no refund. Please take action on them.
