Lancet Acoount still outstanding

My query regarding the Lancet outstanding account for October 2019 is still not settled because the Doctor who is suppose to write a motivation for the claim as per Medshield medical aid request does not respond to my e-mails. As it is Lancet has send me to their SCS with ***. The responsible Dr. is Sobeng Ntlokotsi and her e-mail add. is *** and her number is ***/ office ***. My Medshield ref. number is: 130820Q4B2SX and account number is :FQY18934. This matter is now long overdue. Lancet has the right to do what they have done. The ******** person here is the Dr. .
