I DONT WANT A LEWIS ACCOUNT !!!!!!

I have been inundated with calls from Lewis regarding an account application. After the 1st call I made it VERY clear that I no longer want and account - this was in November. It is now 21 December and I am being hounded with SMS's and calls to complete my application !!! Should I receive another call from Lewis stores - I will report this to the consumer rights board. This is unacceptable.
