Delhivery — Very much delay in product deliy

Hello, I've placed an order from wakefit and they have shipped the product using delhivery logistics, the product is being delayed for the delivery, tried raising many complaints on the delhivery portal but they aren't responding. The expected delivery date is being postponed every day, it's been sitting idle on each warehouse for 2 or more days and then now it's traveling back and forth instead of delivering.
