Myntra.com — executive not coming for pick up of return items

Dear sir/ madam

I have placed a return request for the product on 14th july 2018. Till today no one has come to pick up the products. I receive a message from myntra mentioning a phone no and name of the person who will come for pick up. I called him up and he replies that he doesnot come to my address, some one else will come tomorrow. I received a mssg from myntra that i asked for a reschedule which is not true. Your pick up person didnot come to my place. Next day i receive a mssg from myntra again that a person will come for pick up. After calling twice he picks up my call an says that he will come after 5 pm, however he never turned up. Again i receive a mssg from myntra stating that i requested a reschedule which is again not true. Next day i receive a mssg that person will come for pick up he never came for pick up but repeatedly i m getting mssges that i have requested for a reschedule which is a false messages being send from myntra. Since 5- 6 days i have been making arrangements at my place so that the executive might come for pick up. He never turned up. This has caused a lot of incovenience to me. I had called up the customer care also. Next day i receive a mssg for pick up, mentioning another executive. I tried calling him twice, he didnot respond to my call and never called back. He also didnot come for pick up. But without fail i got a mssg from myntra that i have requested a reschedule. I dont understand why myntra is sending such false messages. Since the time i have placed a request for pick up it has caused me a lot of inconvenience. I am highly disappointed with the service. Before sending such wrong messages dont you confirm what exactly has happened. I am bombarded with messages without any positive outcome. Dont you check if your pick up person is doing his job, causing so much of inconvenience for the customers. I am utterly disappointed with service. Which has made me think if should i buy anything from myntra.
Hope you take stringent steps in this matter and find out exactly what is happening, why executive is not coming for pick up and why false messages are sent to me.
Prompt action is needed.
