After 3 repairs they are still not interested....

I have bought a Samsung Galaxy Tab 3from the Samsung store at Fourways Crossing. When the tablet is working it is an absolute pleasure, and I proceeded to do my banking, Watsapp, email etc. all on this whilst I travel during the day. This is of course when it is working... What the good folks at Samsung never told me is that when the battery goes flat, the tablet has to go to one of their \Care Centers"for a \""Shock Boost\"". This has now happened 3 times in the last two 2 mths. Every time I have to travel to Constantia Kloof from Fourways"
