Letter to Orange Customer Service

My phone appears to have developed a fault.  I keep getting a message which says "Inactive SIM" on the screen.

I have tried turning the phone off and on again, and turning it off removing the battery and SIM and then replacing them and turning the phone back on again.  This seems to solve the problem temporarily but then it reoccurs later.

I tried to call customer services from a landline, and after completing all of the press 1 for this 2 for that, was told that all operators were busy and was cut off.

To say the least I am extremely unhappy.  This is not the first time that I have had a problem with contacting orange, and I am seriously considering leaving once again.

Please can someone contact me to resolve this current problem.

Thank you.

p.s. I can be reached on either 0**** *****7 during the daytime or 0**** *****4 - no point in you calling my mobile because it isn't working again!
