Olx India — Remove number from call list

Address:

India

I had raised a request to sell my car a few months back, olx gave me a decent price first but then later had to decline the deal because they weren’t offering the old price which is fine . But ever since then I get calls from olx autos everyday literally everyday at least 5 times asking if I want to sell my car. I have made it clear I sold my car long time back still they call me and it has become a nuisance. They call during office hours after office hours and even on sundays. I want to remove my contact number from their call list immediately.
