Hathway — Not activating my account after installation done

Address:

Masjidbanda

I took Hathway broadband connection yesterday and the person who installed told me I will receive call with in 3 hours from customer care. But I haven't received any call. I raised a request for activation myself but didn't get any response. I called to the sales person who initiated the process he asked me to send him the photo of my router and then he said he raised a request and it will get activated after 4 hours. But same story repeat now. Now the sales person avoiding my calls and I don't know where to ask for refund. Hathway services are really worst they didn't provide any option for refund in their mobile app or website and they are not even responding for my mails. I have no clue what to do now.
