Booster Purchased & No Feedback All Round

I purchased a booster package of 6 personal training sessions with Andrea on 8 May 2017. The terms were that the trainer gets in touch with you, which didn't happen despite multiple follow-ups from my side, so a lot of time was wasted and the special was closer to its expiry. The club did not communicate with Andrea on this, and the deal was not worthwhile for her. I did the assessment and two 30 minute sessions, and was then informed by the trainer that the rest of my sessions would not be honored. I haven't received my assessment details to this day. Bad service all round. The clubs need to reconsider deals that are not feasible for the trainers. Shouldn't have purchased this, or should have gotten a refund instead. A waste of time and energy.
