Frustrated with The Vital Diagnostic Services Corp.'s lack of response

I am writing regarding order #ORD-4224-DNN-2815 placed with The Vital Diagnostic Services Corp. on March 8, 1974. I paid $569.47 for device, but when it arrived, I discovered experienced frequent disconnections. I've made numerous attempts to contact customer service, but Rosalind D. and other representatives have not been helpful in resolving this matter.
