SERVICE PROVIDERS GIVE PERS INFO - VODACOM

1. ON THE 05/09/2015 AT 10:03, I RECEIVED A MESSAGE FRO A MERCHANT , STATING I WAS AWARDED A SHOPPING VOUCHER R 3 700.00. US THIS LINK TO CLAIM THE REWARD, [URL Removed] TO OPT OUT I MUST SEND A SMS WITH THE WORD STOP OR VISIT THE WEBSITE AND FOLLOW THE PROMPTS, I DID SMS STOP TO OPT OUT. AT 10:11 I DID EXACTLY WHAT WAS TEXT TO ME. STOP. SMS WAS SENT. REASON IS THAT THEY WANT R 7.00 / DAY I CAN NOT DO THIS AS I AM A SICK UNEMPLOYED WOMAN ALONE. THEY EVEN SEND ME A PASSWORD, 555983. I NEVER VISITED THE WEBSITE JUST SEND A SMS STOP. THE REPLY SMS CAME AND STATED YOU ARE UN SUBSCRIBED FROM OUR SERVICE WITH EFFECT 04/09/2015, THE DATE IS ACTUALLY THE DAY BEFORE, WHY I CAN NOT SAY. AFTER THIS ESCAPADE I CALLED MY SISTER TO FIND THAT I HAVE R 2.00 LEFT ON MY PHONE, YET THE MORNING I HAD R 16.00, SO WHAT HAPPENED TO MY R 14.00. I CALLED VODACOM WITH VERY LITTLE HELP, AS LUCY THE OPERATOR TOLD ME THAT IS NOT VODACOM'S PROBLEM WHEN YOU DEAL IN THESE THINGS. SHE SAID SHE WILL UNSUBSCRIBE ME I SAID I AM ALREADY, SO WHAT DO YOU WANT TO DO. I AM CALLING AS YOU PROVIDE SERVICE TO ME WHERE IS MY MONEY? ITS NOT OUR PROBLEM. SO HOW DID THIS MERCHANT GET MY NUMBER AS I AM SUBSCRIBED TO YOU
