"They do not return calls"

Issues with husband's CPAP Machine/Sleep Apnea, trying to contact the clinic for two days, left voicemails, it is now stating no more voicemails can be left due to the amount of voicemails left by myself and others.

They do not return calls, and can not be contacted due to going to voicemail and no one answering calls.

This is absolutely terrible for service that helps with sleep apnea and issues with apneas happening while using the CPAP.
