Samsung no service

We purchased a very expensive Samsung fridge that is giving us problems just over an year old still under warranty. We contacted Samsung on 16-09-2019 and registered a repair claim for a technician to come and do repairs. we received a sms that the technician will attend the following day the 17-09-2019. So the sms still continue to come in every day. We receive a new sms that they will attend the next day. we are now at 23-09-2019 still no one bothered to contact or do the repairs.
