11.09.2015. no activation until know. 3 weeks late

I have paid the amount duo on the 11.09.2015.and the proof off payment and the reactivation forms was send through until know sim card is still not activated, if you call the activation department they just told you the documents was not received but I have proof the was received twice know and each time I had to wait another 7-14 days. this is unacceptable. I need response ASAP.
