Bad service

I have paid the upfront fee of 479 for the unlimited data on the 6th july and not network. I've logged so many complaints but they are not contacting me to solve the problem. Its says out of coverage and we are staying in town and around us there are rain sites. I'm afraid I'm paying for non service and will continue paying for none service as this is the 4th day today and I'm unsuccessful in getting help or assistance. I've logged so many complains.
