Poor and dishonest service

Took my car to Reeds because my handbreak warning light was flashing. I received a call from the service adviser Grant informed that the issue was being seen to and whether I would like my service to be done as well. I said yes please. I was later called by the said service advisor who said that the issue was sorted with the hand brake but I should monitor it to see if something goes wrong then to bring it back. However when I collected the vehicle the vehicle sounded strange when I started it and then went normal after. I then noticed my hand brake light not flashing but permanently on and my hand brake not showing on the system when it's up or down. He told me it normal until its sorted out. That was not what was discussed telephonically and the Reeds service advisor well knew that the issue was far from sorted. Poor and dishonest service. I took my car with an issue to the handbrake which was faulty but working and now I have no handbrake at ALL !!
