I called back number (02) 4323 9100 rang once then goes to busy tone.

This company just abused their right to contact me by sending me a text today when I had an appointment at a completely different facility - they even answered the phone and said that my appointment was confirmed. I know exactly where my appointment was made and it was NOT with them. They send me a text from the same mobile number as a French restaurant where we had a meal not too long ago. I thought strange but the landline no was not the same as where my booking was. Well those fools don't realise that I don't have a back or spinal problem!
