Meshoo - My return request was cancel

pick up was done in last week of march, but pickup partner said he does have any option to return your product, so today he has delivered it to me again.
So, form the one month, I have been continually coordinating with meshoo team, but till now they have not solved my issue. Instead of raising a complaint, they have not done anything.
On every call, they say just within *-* days, it will be solved. I am literally frustrated having to continually discuss with their team and senior person. team and senior person time on same stage, same sentence. A solution has not been given till date. if you check my record, i have tabe on call me back **-** times.

Do you have any grievance policies, procedures, or committees?

For all the above questions, I need a reply from your management. From the beginning to today, if you need any clarification or evidence, let me know.
Note: Please do not make a fake promise to your customer.
