Swiggy & Hangout - Regarding the horrible service provided by swiggy

Around *:**pm I had placed an order with Hangout cakes & more.that was a pineapple *kg cake which arrived at *:**pm.when we opened the package we received a cake which was completely damaged and not re-presentable . So I clicked the picture of the cake and forwarded to the swiggy customer department. Where I spoke to MR. Somit he insured me that the cake would be replaced and gave me the following order no *********** and it will be delivered in **mins( chat was done at(*:**pm) as well as he tld me that its my call if I want to return the spoiled cake or keep it. Then I got a call from the delivery guy who handovered the call to the vendor. Vendor said that I can replace the half kg cake which costed ***. Where as I had placed as well as received *kg cake amounted RS ***.I paid the delivery guy *** which was completely paid through cash. Where as vendor refused to replace the *kg cake only agreed to replace half kg coz it was the swiggy guys fault since in hangout menu *kg option isnt available the swiggy guy paid him ***rs which was displaced in the swiggy app receipt.but delivered us *kg cake and took entire ***rs also vendor as well as swiggy didn't provide us the receipt of the *kg cake order. In between this a lady called me from ********** number and was so arrogant, mannerless as well as illiterate to be in a customer service background and doesn't have any ethics how to handle upset and not-satisfied clients. She was forcing us to cancel the replacement order and later without are permission she cancelled our order and disconnected the line. So I called the customer service spoke to * people MAYANK, NEHA & Team leader Mr. NIKHIL so finally after having a long *hr call the conclusion was no replacement and we will be provided their shitty coupons. Such brainless heads still think that after receiving a bad product, bad customer service we would still use their app.at the end its not about the money its about the time we wasted and the occasion was spoil.
