Limeroad — return delayed

Address: Vidyavihar West, 400086

I had purchased a kurti from lime road for the first time. And received it on time[protected]. But i didn't like the kurti as it is not came to my expectation.
So i initiated a return on the same day that item had delivered[protected].
The tracking details shown that return will be pickup within 2 days.
Till today nobody came for pickup. I had called the customer care center many times. They said, pickup will arrange tomorrow. Many 'tomorrows' are gone, till now nothing had happen.
Since the last 8 days i had taken followup on this, and today again message had came from lime road saying due to operational delay pickup is expected to be delayed by 2 days.
Can you please explain me what is operational delay means?.
Even i had called the pickup man number that they have shared through sms, everyday and asked him when i can expect the return.
He is saying, 'i am near to your pickup location and will be reach by 1 hr'.

Kindly help.
