Poor customer service

It's the 3rd day still trying to connect the router... I called, I sent messages on Twitter and also sent emails... It's really annoying to be sending documents now and again being helped my different people.. The router was delivered Sat and the delivery guy did RICA the Sim... I called and they didn't help much... Sent DM on Twitter and was told the SIM was not registered... I went to the store myself yesterday to RICA and even got welcome SMS. now I'm told the sim is not registered... It's getting tiring and I no longer want the router.
