Bad service

Bought a Phillips shaver from clicks on 2017-01-03 Jeffreys bay. As I only use it when I go on holiday or weekends away it was stored for about 2 months since I last used it. When I took it out 2 weeks ago it did not want to come on even tough it was fully charged. I took it to Clicks in Jeffreys bay and was told they would replace it. Unfortunately I did not have the charger with me thus the could not complete the transaction. When I went back Saturday 2018-12 15 for the promised exchange I was told that I must send the product to Philips myself and that they will not do an exchange at the store despite the assurance by them a week ago. Should I now send the product Philips will only receive it well after the expiry date on the warranty.... I tried to mail this queries to the Clicks help e-mail without any success as it just give an error report upon sending
