Accountability lost

I have placed a SIM order on 10.07.2020, and was promised delivery within 5 days. The courier company RAM was appointed for this delivery. They send me an SMS on 14.07.2020 and also 15.07.2020. Since then no communication was made, until I started phoning on 20.07.2020 speaking to 4 different consultants per call that I made, with no satisfactory feedback. Two of the calls were dropped. On 21.07.2020 I spoke to a very dedicated consultant who came back to me with a feedback that the SIM has been lost by the driver, and that they have requested a replacement one. On the same day, I received an SMS from Rain to congratulate me on the activation of the SIM. I immediately responded to them that I have not received the SIM. I also went to send the query online, and nothing has been coming from them. Their turnaround is too long for the type of service that they are providing. I tried looking for email address of the CEO's of both companies, and could not find them.
