Service Suzuki Swift at Suzuki Hatfield

I took my Suzuki Swift for its first service the 16 February 2022 all well and done. But the next morning I discovered a oil leak where my vehicle were parked and the noise I said was not fixed. After I received a courtesy call the next day I complaint about it. The service manager phoned me back that afternoon but their was no time that they can look but they will come and get my car the Friday. In the meen time I discovered that the sump plug was not titend and that is the oil leak. They came and fetched my car Friday and done everything but then they phone me and told my my car was bumped but they will fix it till today have not heard any thing from Suzuki Hatfield
