STILL NO INTERNET

After MANY attempts to get some assistance with my router that says no service..the problem is STILL not solved, i even wrote a review a few weeks back on this site and received a reply that they will see to the problem...no one at the Telkom store, call centre or Hello peter are able to assist me...store managers just dont call me back and are never available either.....i cannot keep wasting time and money like this!!! This is absolutely unacceptable service.. my wifi has not been working for a month now and no help!!! can someone PLEASE assist me to get my internet working??????
