Faulty Breast Pump

I purchased an electric breast pump at babiesrus Clearwater in June. On Friday the 24th October it just stopped working. When I switch it on it searches and doesn't give me option to select mode I want to use. I returned to the store with the receipt I was told to wait for the Rep to assess it. The Rep comes once a week. I have been left inconvenienced in the meantime. Rosy (Store Manager) called customer care ,relayed the story and was told I should return the pump to Woodmead. Imagine the inconvenience once again. I am really disappointed at the service from Philips Avent. I send a query to Instagram page and was told my case has been escalated to the service team which will be in contact ASAP. I still have not yet received any assistance.
