Sweet Deals Cumulus

After reading all the "fine print", twice, I purchased 6 vouchers for services at Spa Sydell. Upon making a reservation for my second spa visit, I was asked for the voucher#. After proving the voucher details the Spa Sydell Rep mentions I only have use of one more voucher. How is this possible when I read the "fine print" prior to purchase and there was NO MENTION of usage limits other than only one per day, and the obvious expiration date of January 1,2019? The Rep informs me that Spa Sydell made a decision to limit customers using these vouchers to only THREE services PER YEAR! Nowhere in Sweet Deals "fine print" does it say only three vouchers can be used per year.
I initially contacted SweetDeals via the methods outlined on its website early July. After no response, I send a second email on July 24th, and made it clear I will expose this matter to the BBB and as many social media sites as possible. Miracle! SweetDeal finally acknowledges my email/complaint on July 25th; however no resolution. It's now August 20th and although I've received communication on August 17th it vaguely stating something that sounds like there might be a solution. I've asked for clarity/verification so there is no misunderstanding when I contact Spa Sydell.
My suggestion- prior to making a purchase of some experience or very important, I suggest carefully reading the fine print, then contact the Vendor to be sure they are in agreement.
