Extremely Angry

I am very disappointed by the service I keep on receiving from rain 1st I have struggled to get the loop activated eventually after a week there was connection now the unlimited simcard does not work it shows offline and I was not even explained what and where. There is no name and password for the WiFi I néed to share hotspot with my phone coz the simcard is not picking up and I don't know where the or what the password is. Nothing is on the loop I asked ask rain and they said I should download the loop app but it's not available I don't know how to go about I was told they going to call me urgently but no one ever calls. They can not expect me to pay for such **** services.
