Terrible service - phones not answered

Unfortunately accepted a router with SIM card offer. Delivered last Wednesday. Continuos promises from Michaela, Senta and obnoxious Gabriel who felt it necessary to make a joke out of the situation! Promised again & again that sim would be activated, after holding on to a number that never gets answered, I am no further to having this white piece of plastic stand on my desk, which I am not able to make any use of without an active SIM card. The sales person Mishfika made sure she gave me \HER"contact number if I have any problems. Only to be told that you cannot be put through to her but have to speak to who ever answers the call and promises you the world and just the same as the previous person"
