Pathetic Client service from Renault

On Friday the the 23rd of August I called Renault multi franchise Tokia regarding my hand brake light and alarm that continuously comes on whilst driving. upon calling them the reception lady tells me that everyone is busy and that she will let them know to contact me urgently regarding my concern. to date I haven't received a call from them even when she told me shed mark it as urgent. I have such a problem with this car and the ombudsman is taking their own sweet time assisting me to deal with this matter for more than a year now. I found that this car has bad workmanship a few weeks ago as well and Renault and my complaints are not being dealt with. I am so fed up of Renault and this car I am driving. I wish there was some way I could take these people to task for the pathetic service I have received since day one.
