At Home Diva — diva hair colour service

Address:

218, Dwarka Trinity, dodda Basvanpura, Seegehalli main road,, K R Puram, 560049

I have taken the service from diva in june. I took global hair color with global hair highlights. My highlights were not at all visible. I made calls to them. But every time they sent me the mail that they are able to contact me.
When they have to give service, they make sure of giving calls number of times but when it's about complain no response.
When they have to sell membership they are behind you.

Now i also i trying to chase them but no response and no refund.
I will suggest not to use service from such an unprofessional company.
