RAIN SIM POOR SERVICES ON CANCELLATION

Rain I'm not a happy client at all, my account is on -R4400. I went to your Rain app and did a cancelation till today not canceled. Your call Centre is not picking up calls. I'm not happy at all with your services. You only give people attention when they want to join rain but when they want to leave it for other better services providers you are not giving them attention. I ONCE GOT THIS RUDE INDIAN LADY (REGGY)I EXPLAINED TO HER MY ISSUE AND EVEN GAVE HER REFERENCE NUMBERS AND ALL SHE SAID WAS SOMOENE FROM ACCOUNTS WILL CALL YOU AND DROPPED MY CALL
