Alarm going off all the time now

[spongebob]

When i bought the car i drove it home, Parked it up a few mins later the alarm went off, I thought i havnt pressed the right button so unlocked it and then locked it again.

This was last Sunday, Since then until today the car has not been opened at all.
Went out in it today and since parking it i have turned the alarm off 5 times, Reshut all the doors and boot but still it goes off.

After reading on here of others having problems of this nature i am not looking forward to trying to sleep tonight.

If it continues to happen i shall take the car back and reject it for a full refund.
