I have purchased Singer promise 1412 sewing machine on 02.08.2022 through Flipkart for domistic purpose. From that day I am faceing a problem. Motor movement in slow motion is not functioning properly. I am pressing foot accelerator for start but machine is not moving until and unless I turn the right wheel by hand and bown bown sound is coming . Again pushing foot pressure high that time machine is starting with high speed as a result yarn is cutting in all time . It is very emberesing to put yarn into the needel hole again and again . Afterall slow motoin is not functionig from the starting point. I think it is a nanufacturing defect. How I solve the problem.
