Poor service, no customer feedback on repairs to vehicle that is still under warranty

On 13 April 2021, I took my vehicle to Suzuki Montana. I was told that my vehicle had a gearbox issue that would require the vehicle to with the dealer for 2 to 4 days. I arranged to drop the vehicle on the 19th for the repairs to be done. There was no feedback from the dealer and I had to phone on Tuesday to get feedback. The person dealing with my issue was not in and she contacted me on Wednesday 21st. I was told that they had to check and get approval first from Warranty and then order the parts. On 22nd I phoned to get feedback and was told she would check and I call me back. Four days later, I still do not have any feedback or clarity on when the vehicle will be ready.
