Receiving bad service trying to get my vehicle repaired

<p>I bought my car in December 2016, there was an agreement that they will repair everything. When taking delivery of the vehicle they informed me that there was a part that they ordered but will take 14 workings days therefore I can take delivery of the vehicle as they will let me know when I can take my car in to get this repair. When driving my car I have notice more problems that was not repaired as they had promised, offer a month not getting any feedback I started emailing and phoning them and still struggling.</p>
