I have purchased a singer sewing machine with serial number [protected] model: sew delight from incs canteen naval base visakhapatnam on[protected]. It is not working. While i am trying to sew thread starts to wound in lower bubbin and machine stops. Therefore i am unable to sew due to this problem which is very bad for me because more sewing is pending which has been planned before purchasing of this new machine.
Please send an operator to solve my problem.
