In case anyone is still deciding whether or not to take lessons there, I took lessons for about a year last year but decided to leave after they repeatedly failed to inform me that my lesson had been cancelled. I would arrive at the centre with my instrument and everything only to be informed that my instructor would not be coming in. This happened a total of 3 times. I finally left because they let it happen twice in a single week, and one of the front desk admins (they kept changing) was particularly insincere and offered no apology which just made things worse. I've been trying to claim back the fees for my last lesson which was not carried out by no fault of mine, but they (I think another front desk admin handling the email account who did not leave a name, very professional indeed) have been unhelpful so far - they provided an insincere and generic reply saying that no records have been kept.
If it is indeed true that no records have been kept of both my activities and the instructor's activities at the centre, this is a sign that the business is falling down from within. Such lax attitudes towards record-keeping can only mean trouble for the consumer. If, on the other hand, they have been keeping records but have lied to avoid providing a refund (and I have reason to suspect that this is true because I signed off after every lesson without fail), then this is plain dishonesty. The money itself is a small sum and I would have let it go if they had given a sincere and detailed explanation and apology. Unfortunately, they have been uncooperative and consistent in ignoring my requests. I can only conclude that they have no regard for their customers and would strongly discourage any one from signing up.
