Bad After Sale Service

I Bought a car from Renault Route 24 about a year ago and they were supposed to install a tracker in my car but the tracking company took to long so my insurance went up, then i asked Renault just to refund that money into the loan account seeing that i didn't receive my tracker and i just assumed that they did it, 10 months later the tracking company phones me and says they still need to install my tracker after i thought that Renault sorted it out then i checked all my statements over the past year and saw Renault didn't do anything.<br> <br> So i maild them and asked them to refund the money into my account so that i can pay it into the loan account, and its been over a week now and still haven't heard anything.<br> <br> Easy to sell a car but After Sale Service is key.
