Worst service ever

<p>A few months back my dad purchased a heart condition monitoring machine from this company. The machine stopped working whilst it was within its 2 year garantee, my dad returned the machine and they took it. I'm it's been 5 months we waiting for the new one. They keep giving us the run around telling us to contact the manufacturer Medinox, the manufacturer has lied to us countless times saying the machine is on it way. Please assist as this is getting out of hand.</p>
