Poor dishonest service

I would like to complain about poor service that we have experienced with your company. <br> Your driver picked us up on 23 December without a baby seat that we requested. Your office informed us that we could use our own seat and assured that our seat will be kept safe in your office and that it won't be used by someone else. <br> We are driving back home now and our baby seat has clearly been used by someone else since it contains baby sunglasses and lip gloss. <br> This is poor and ********* service. <br>
