No service

Very bad customer service, received my sim and modem 25 June but have no service at my home, called them and they said we can return device if we are unhappy within 7days,they asked me the give them 48 hours to do repairs on the network but still no service, called multiple times to cancel /return the device but every time they say network technicians will come to test tower, spoke to a supervisor call Owen and he promised to get service working or he will arrange pickup of the device but still no joy and you can call but Owen is always unavailable now
