We bought a siemens coffee machine in August from Hirshes. The Siemens consultant first of all never sold us water purifier for the machine so we had ro go back for that. Secondly he said we will get within 1 week a complimentary cleaning pack delivered to us. Which we registered for. We have followed up on numerous occasions with Hirshes, Siemens directly as well as the sales consultant for Siemens. Items advertised with a over R12 000 purchased are just not adhered to, follow up service is just non existing.. I am in disbelief that such a well known brand has such little customer service
