Battery dead at home, should I just book a doorstep replacement?

[primitivoconner]

My car has been parked outside for a few days and this morning it only clicked when I tried to start it. The battery has felt weak for a while so I'm pretty sure it's gone, and honestly I don't want to spend the afternoon jump starting it and hunting for a garage in this heat. A colleague mentioned you can get a Mobile Car Battery Replacement at your home or office, which sounds much less hassle. Has anyone tried this kind of doorstep service in the UAE? I'm mainly wondering if they're reliable and whether the price ends up being reasonable compared to just towing it somewhere.
