No feedback as promised

I sent a quote to your heath info email address as requested by your call centre. I just want to know if a procedure my husband is going in for will be covered. All the details are on the quote, why they could not tell me over the phone is one thing, but then to be completely ignored over email makes me furious. Its a simple yes or no and how it will be covered. Dont lie to your customer by telling them you will respond in 1-3 business days. It is now 5 days since ive sent that mail. PLEASE RESPOND as its almost time for him to go in. Its really shocking that this kind of info can't be given over the phone.
