Mark and the team at Portcullis are pivotal in supporting the high standard of customer service we as a company set ourselves (Cummins Power Generation) The extensive service given to both VIP customers & internal staff is second to none but the 'over and above' level of support that is given by Mark is an added bonus. Mark is extremely proactive in his approach when taking on all our needs and has been a godsend in so many situations. The reaction and response times are faultless, as is his professional approach to every situation! Portcullis have always come through for us (NEVER not accepting a booking & never leaving anyone stranded - even in the stickiest of situations) and this is a great testament to the first class service Mark and his team provide! Thank- you Portcullis.. Laura, Helen, Tracy, Rebecca & Susan - Cummins Power Generation
