Can only make a booking online

My iPad keeps loosing the Wi-fi address and I cannot access notes. I went into Clearwater branch this morning and was told they cannot book a consultant, I must do it on line. To do this I have to create an account which I do not want to do. I have phoned the number I was given twice and was told the call cannot be transferred and to phone again later. I have an iPad that is useless and not up to what Apple products are made to be. Sadly I feel that the store also did not care. I cannot find where I can lodge a complaint directly to them on their website.
