Still no response from Discovery Health?

Regrettably having to post up another complaint on top of my first complaint dated 28th March. Discovery sent what looked like a standard reply on the same day with a promise of feedback asap but up until today, no further correspondence either in writing or via cell phone. Understanding the challenges around public holidays over the past week, I still find it unacceptable that nobody has contacted me after close to two full working days on my query. Please can someone contact me to discuss my dispute, I am worried and deeply concerned about my outstanding matter. Regards Daniel Weston
