TESTIMONIALS FROM TRUSTPILOT
Excellent customer service support…
"Testing all very straightforward and both kit and results came through no problem. I also used the chat service a couple of times just to clarify things and also because i needed another copy of the invoice. Deepthi was excellent - clear, efficient and got me what i needed. Many thanks - would definitely use you again."
- Judith
