Keypad not Selecting Options

[MichDC]

If I phone a service that requires me to pick an option to get through to a specific department, I press the number but it's not doing anything. I've tried different numbers or a symbol but it just keeps repeating the options as it's not registering my choice I have reboot the phone more than once, also tried it whilst hands free in the car and using the cars on screen keypad. Still nothing. Need to contact people but can't choose an option.
