We our customers

Here's what they say about us:

GSA Business Development, was contracted by the Hong Kong Trade Development Council from November 2017 to May 2018 to provide telemarketing services for our GDPR consent campaign in the markets covered by this office. GSA called a total of 74,000 records and managed to secure a good consent rate. The company was responsive and always willing to listen to our fears and concerns. GSA is a cool-minded and professional TM agency, and I was happy with the results that they obtained. GSA was awarded the contract on the basis of a competitive tender, and so their costs were reasonable. Thanks to their efforts, we managed to cover our databank before the deadline of 25 May. I would happily appoint them again. All things being equal. David Marsden- Director UK, Benelux & Ireland Hong Kong Trade and Development Council (HKTDC)
"I am delighted with how this has turned out, it is exactly what I wanted. I realize that it wasn't the easiest task in the world today and I sincerely hope that as the months go on it becomes easier for you." Trading Supervisor Foreign Exchange Company
"Just wanted to say thanks to Jonathan and the team for all of their efforts to put us infront of the people we need to do business with. Lead generation is always a challenge and GSA enabled us to increase the number of leads into our business. I was very pleased with the professional service and results and Carol is brilliant. I look forward to working with you again in the future" Sale Director DCS (London) Limited
