Where to service a GranGaggia espresso machine in JHB?

[kinosfronimos]

We have a fairly old GranGaggia manual coffee machine which we suspect could do with a service (although it still pulls a good coffee).

Is is this model: https://www.adverts.ie/small-kitchen-appliances/vintage-grangaggia-coffee-machine/15168998

Any pointers on who in JHB could/would expertly service such a machine?
Tx!
