Good Living LED Bulbs

I have bought 13 of these LED Bulbs from Spar, after one month one stopped working. I went back to the store with the receipt to show the Manager when i bought it, I had no problem he gladly replaced it.. Then another one blew i went back to the store, I told the Manager this one has blew also, he informed me I need to get hold of Customer Service. I emailed Spar Customer Service I had an email back to say I must take the LED bulb back to the store and the Store Representative will pick it up which i was informed he did. After numerous emails to Spar Customer Service, it's now a month later and i haven't any contact from the Store or the Rep for the LED Bulbs. On the box there guarantee is 25,000 hours which equates to +- 2.8 years. No one is coming back to me not even Customer Service i'm sending emails and no feedback. Who ever supply these LED Bulbs to Spars need to get there act together or Spar must find another supplier, **** product and really unhappy with Spar and there Service.
