Edge Coils NOT lasting / BAD Customer Service

Again, my second complaint, your coils does not last. 1 Week max. 6-8 weeks a joke! After all the tips & tricks via you (head office) & Twisp Kiosk employers, you need to sort this out! Also had to replace my Black battery twice, my whole device to Silver after that. Yes, I wick it, charge it overnight via USB, keep it at 4-4.2, & use minimally, so what then? ALSO, your loyalty programme? What a joke, I use my fianc?es number, as my account is a joke (registered, updated & always just 2 points) after NUMEROUS purchases. According to YOU after the 7th liquid purchase you get one for free? 2 Weeks ago I was at Centurion Mall, I was on 6 points. Last week Friday (after I had to get yet ANOTHER coil) I bought another liquid at OR Tambo, oh & what a surprise, your system shows only 2 POINTS!!! I made them print out all invoices, clearly they could see I was entitled to my 8th liquid free but couldn't because of YOUR GREAT loyalty system showing only 2 points. SORT THIS OUT!!! I'm tired of complaining & tired of being taken for a ride!!! This is not a cheap exercise!!!
