We our customers

Here's what they say about us:

"We worked with GSA over two campaigns for more than a year and they provided us with high-quality telemarketing services. This has allowed us to keep a consistent flow of sales leads into blue-chip organisations from which we have generated new business. I would recommend GSA to any company looking to develop new business" Chief Executive London PR agency
“GSA took on board our comprehensive brief and provided an excellent service from campaign inception through to analysis upon completion. We were particularly impressed by the professionalism and telephone manner of Julia March in conducting the calls to medical staff. Julia was quick to understand our technology and the correct terminology to use, with her distinct conversational tone helping to sell the benefits and uses of our speech privacy systems rather than focusing on the product. Likewise, the communications from both Julia and Kevin Harmsworth throughout ensured we remained fully up to date with progress, even when the campaign was temporarily put on hold to garner better results later in the year.” Steve Rees-Smith, Marketing/PR Vaughan Sound Installations Ltd
"GSA carried out a telemarketing campaign for us that was extended beyond original time frame. They provided our company with a first class service during that time and we would happily use them in the future for other telemarketing projects. Sam has been an absolute delight to work with during her time working on our telemarketing project. She understood our business incredibly well and also knew how to build relations with our target prospects. Her approach was perfect and she really was an extension of our marketing team. As a result of her calling we have a major PITCH with one of our top targets at end of June." Business Development Director London PR agency
