SRL Diagnostics — No response on Scheduled and paid visit

Address:

Gurgaon, palam vihar

On 5 th June I booked order no.: MUF080396 & MUF080394 for 6 th June 7-8 am. I still haven't received any confirmation on June 7 haven't received any confirmation about who will collect sample. What is the purpose of scheduling if the team doesn't follow it? It's highly disappointing service.
Never booking it again.
I also paid in advance, if the service is not given by 8 June, cancel and refund the exact total amount
