Clove dental - Ineffective dental Treatment

I have toothache and I visited their clinic in sector -**, Rohini , Delhi-** . I am visiting Clove Dental for treatment for more than * months now. I went to Clove thinking they are better and accountable than road side dental clinics. I enrolled for their membership also which they suggested would help me save some money . After numerous visits also no relief from pain . Doctors say they are not able to diagnose the real cause of pain . They suggested I do root canalling. I agreed for that and I paid approximately **** Rs and underwent root canalling. . Apart from that I did * OPGs , Scanning and OBCT Scanning also which is costly ( Rs ****/) . I have so far spent more than *****/ . End result is that the pain in the tooth has only worsened . I am unable to eat from that side. Eating pain killers to subdue the pain . How long this is going to continue . Doctors in clove say yours is a different case and we are unable to diagnose the real cause or real tooth that is causing the pain. This is their explanation. My time , my money and my health has only deteriorated . Somebody needs to own up .
