I bought Psiloc System Tools for my Sendo X, mainly for the "flight mode" function. Their website says this works with the Sendo X; it doesn't. I sent them two emails asking them to either fix it for my handset or give me a refund. No reply.
The advertised price on their website is 9.95 Euro; I just got a credit card bill for 8.01 GBP, which is not 9.95 Euro.
I shall be disputing the payment with my credit card company and posting this to all the Symbian forums I can find.
