I bought IPL treatment to Alla salon, tried to phone and SMS many times, their respond was that machine broken and takes few weeks to fix. After month negotiation i came to the conclusion that this is scam. I contacted groupon to refund my $ 70.00 back. They refused on offered trade in to groupon account when i tried to trade for new deal its appear the $70 was not deposited to the account. The customer service has no phone contact only through e-mails which they don't respond anyways... I will not buy any more from groupon
