Home Centre — Not delivering product on time

I have ordered three products from home centre online on 15th of june 2020. It was supposed to be delivered on 5th july 2020. After this date i approached customer care service they said you will get it by 14th july coz they have started their delivery on 7th of july. I said ok accepted... Then after this date i have again contacted them, from their onwards they have started giving excuses... I have all the complain numbers and names of people with whom i spoke and are highly unprofessional people who are sitting in customer care center... First complain no...561209, 567298, 5710771... I spoke to laxmi, rajesh, mani and many more... Then i have 581244 n name of person is anita…. Then on 10th aug i again spoke to them with complain no 643649 but they have given me same excuse that thy will escalate the matter to delivery team,... But all in vain... Coz they will not be doing anything and will be coming up with more excuses... So now as a customer who is being mentally harassed by home centre want my money back..
