JIO FIBRE - Service not provided

I requested them to transfer my Jio Fibre connection from my old address to a new address on *st April as I need connection on *rd April as i am shifting to new house on *th April. They denied it & told due to unavoidable technical reasons they are unable to process my request for relocation. As my new address is feasible and asked me to take a new JioFiber connection. they will be able to process your request by **th April ****. After **th april, they repeated the same thing again & told me will be able to process by **nd April ****. After **nd april, they repeated the same thing again & told me will be able to process by **th April ****.

Even I called to customer care but they repeated the same thing again. Before taking their connection, I asked them if relocation is posibble to which they agreed.
Now not only they denied to transfer my connection but told me to take a new connection OR cancel entirely. Is this the way of cheating to customers? Either I want the connection to be installed in my new house or give me the refund. This happened in Chennai.
