Cresta Virgin Active - Ignores feedback

On 3 consecutive weeks I completed a feedback card at the reception of Cresta Virgin Active. Coincidentally soon thereafter I received a link to a Virgin Active on-line survey which resulted in an e-mail from the Branch Manager. I have tried to see the Manager but he has been out / not available. I have invited him to call me and get details of my concerns. No call has been received. Only plausible conclusion: Cresta Virgin Active management is not interested in getting feedback. The feedback card system at reception is merely window dressing.
