VERY BAD CUSTOMER SERVICE

My internet does not work even if I sent request for customer service.I phoned them numerous times the technical team was suppose to phone me 2 weeks ago but still no phone call from them.The customer care people do not care there was one person that was helpful and he confirmed that my router is faulty and I was also told 2 to 3 months ago my router is faulty but they do no effort to replace the router.
