V Care — Complaint regarding improper treatment and staff's irresponsible behavior

I have reached out to v care for strech marks removal treatment and in appointment they confirmed me that it fades after sittings even I double checked. I believed in v care and went ahead with further treatment for 38000 with bajajfinserv EMI.Hope this is not the small amount. I have told for my arms and abdomen strech marks. In 1st and 2nd sitting they treated only abdomen strech marks and gave cream for arm strech marks and said to use for 3months and asked treatment for arms they said by using this cream it will fade. I used this for 3months, there was no reaction on my skin. On 2nd sitting they locked me inside the small room after applying cream on abdomen no one came and checked and just wiped the cream after 45mnts and gone out and scolded them this is how they treated me on 2nd sitting. On 3rd sitting, they said that the machine was repair and didnt do that siiting properly. Then i raised complaint about the2nd and 3rd sitting but there was no response in RS puram branch. 3rd sitting was taken in sungam branch. On 4th sitting they gave me on arm and abdomen due to complaint but they didnt do well, again i complaint about the treatment and took the photos of the treatment and shown with the doctor, she said that hereafter ill take care and came for 5th sitting, there she was using her mobile and chatting with therapist
And again I made a complaint of 4th and 5th sitting but there was no response, so I shifted to sungam branch again i faced the same problem and raised the complaint but there was no response, again i went for 7th sitting at sungam complaint to manager but there was no response. On 7th sitting i am okay with siiting but imporer sitting (in some places on abdomen the treatemnt was not done) and the therapist used the phone while treatment so again i raised the complaint and they said the amount i paid only for abdomen not for arms they said on 7th sitting if so why they suggested cream for arms if i dont said arms, they are cheating, however later I felt bad and raised a complaint and called RS puram branch they said, I'll call you back...
I called them...I messaged them s many times...but their reply was ill get you back mam...but no call back. On 2nd sitting bajajfinserv have taken amount 2times from my account, so I called RS puram branch but they didn't even respond me, I called them atleast 10times...this is the behavior of the manager and the doctor and the therapist. I need a solution for this which I got stressed.
