SRL Diagnostics — refund not received yet

Address:

k 602, Amrapali zodiac sector 120 Noida, Gautam Buddh Nagar, Uttar Pradesh, 201301

I had booked a home sample collection for my daughter on[protected]. I had already made the payment of 1883/- on their srl app via online mode. As my daughter is under 5 years of age so they refused to come for home collection. So i cancelled the appointment on[protected]. Then i called up customer care & asked for the refund. He told me that within 7-8 working days you will get your refund. Now it's been more than 20 days & i have not received my money yet into my a/c. I chasing them like hell but no one is providing me the solution. Every time i got the same reply that "i will arrange a call back & get it resolved in a couple of days".
If such kind of pathetic services are providing by them then i am sure that not only i, there must be so many others who are suffering from them every day. I am pretty much sure that people will start withdrawing services soon if this continues & will not be relying on their app & making payment online. Hope this complaint will surely reach to the concern member or owner of srl diagnostics. As i need justification in delay in refund process & want compensation for the pain that i have taken to chase it.
