@bspr sir,
Raj Electroniks here, is Rajiv Ji's eBay shop name; A Noun. Thus as per thumb rule, he can spell it as he wants. Electroniks, Elektronics or Electrauniks. Here you are wrong.
About your voucher, I agree and disagree to it both. It was your mistake and it wasn't. when you order at dominos, dont you anounce your voucher code? or do you get the discount without telling them that you have the voucher code?
Discount code is a privilege to a buyer, not his universal right. So if you are privileged announce it.
And the reason, no body is bothering to respond back to you is, you are telling every one they are rude, however, with your mails, with all due respect to you. You have certainly made rude comments to fellow and senior members more than once.
Kindly be nice to every one. You will get discount voucher again, but support of senior members is hard to find.
