I’m sorry for your bad experience. I bought a 3.5” Morphy set from SC prior to the pandemic. There was an issue which Mandeep resolved for me. I was satisfied with the result. A lot of others including yourself have reported some issues dealing with Mandeep since that time. I hope you get your situation resolved.
On a side note, I just ordered another set from Mandeep this morning. I expect the worst but hope for the best.

Please also note their return policy is misleading. Anyone who reads it would certainly feel they can return the set as long as it is new, unworn etc. not the case, only if it has some defects as I was explained by stautoncastle. Pointing them to what they stated in their return policy did not help, they just brushed me off and moved on.
Look for other products and companies, they have much better product with better return. The one ordered looked great on pics, the real thing was awful.
Very unhappy customer.
