A small update; Still silent from King's support team. Wrote about four times to them .. So now I can really forget about getting my boosters back. The "Support" team really sucks!
I purchased the milestone package for reaching Level 1415 but never received the advertised boosters. I've emailed 3 times already and sent a copy of the screenshot purchase from Google Play but I have yet to receive a response. Please help. If I can't get the boosters, then please credit my account back.
