Poor connection and service from rain5G

I decided to contact rain's customer service on the 081 number to solve my connection problem, I was told that I'm far from the towers, unless if the towers have moved but my residence is still the same because it has been 3 weeks that I have been experiencing bad connection or no internet connection at all and this was not an issue since I have upgraded to 5G. The poor consultant had no idea what to say and that's because she was all the way in India. This need to be resolved and improved ASAP, we can't get work done from home with a such an unreliable internet service provider. We upgraded to 5G because it was promised to be faster and no buffering but we got worse " no connection".
