POOOR CUSTOMER SERVICE FROM RAIN INTERNET SERVICE PROVIDER

I am very disappointed with Rain service and network. I took up the rain package of R479 which is 4G. According to their website my address do have rain coverage, I am in town cbd and i Stay in the flat on the 2nd floor so when i activated their sim I was on the 7th of the building when I went into my flat, No network. I was shocked as i just paid so much money for something that does work from day one. Over the weekend I went home Umgababa South coast of durban even there is no network that when started to really started to get frustrated as I cant use the sim in my flat neither at home so what is the use of having it. Rain on their website says if you cancel within 7days of activating data they will Refund you the full amount. Friday I logged the ticket of number ***5 and IMMEDIATELY received an email stating an agent will call me with 24hours. The whole 24 hours went by no contact just 30minute before the end of the 24hour period i logged another call ticket number ***7 and even rep**** to their email request feedback in this matter. NO ONE CAME BACK TO ME. On the 6th I logged another ticket number ***5 and received the same email but still no one came back to me. yester day i logged another ticket number ***6 and till now no one bothered to contact me. I am feed up with Rain their service is just like their signature poor. I WANT MY REFUND I AM NOT USING THEIR SERVICE, EVEN THEIR SIM CARD IS NOT BEING USED ANY MORE. ALL I WANT IS MY R479 SIMPLY BECAUSE I DIDNT USE THEIR DATA. YOU FAIL TO EVEN FOLLOW UP ON CUSTOMER COMPLAINS. WHY SAY YOU CONTACT PERSON WITHIN 24HOURS AND DONT BOTHER TO DO SO AND THE WHOLE 86HOURS GOES BY AND NO FEEDBACK. I WANT MY REFUND PLEASE.
