This is with reference to order number.RDF40182243
I have ordered apple adapter on 26th September 2022, delivery showed my 28th September 2022, but in the app delivery status is not showing and I even complaint about it, they are not even responding to complaint, till date I didn't receive my order neither they are confirming about the delivery date, pathetic services they have, customer care is totally useless can not expect this from a company like reliance.
I requested them even I can pick this order from stores near by my house they are not even helping for this.
