Philips India — Replacement of sleep apnea machine

My DreamMapper Go needs replacement foams and I’ve been informed that this shall happen in mid-October. Firstly, given that this machine is used to treat sleep apnea, this delayed servicing is callous, to say the least. Philips should be replacing the foam immediately, so as to avoid inconvenience to the patient, rather than mouth an apology and leave the customer helpless. This is an expensive machine and better service would have been appreciated. Moreover, this is a travel machine, how shall any patient sleep while travelling? Or is that of no consequence to Philips India?
