Livpure — RO Leakage - Complaint was cancelled without fixing or any notice

No engineer visited till now and my previous complaint JS [protected] cancelled without any notice and no one has come to fix the issue. I paid for ACMC in DEC 2020 and it was not activated till yesterday. I haven't seen such a worst service support. Engineer Pamila Rajender (pH no. [protected]) is least bothered to attend my complaint no matter how many times I followed up with him. I have been looking for further escalation process over online support so it reaches higher authorities to know what kind of service customers are receiving. Please send the engineer on priority.
