YOU HAD ONE TASK!!!!!

I went into a Vodacom Store at Cape Gate Centre to change my physical address. Two weeks later I called Call Centre to send me a statement via emaIl. Which they are suppose to do anyway without asking. Only to discover that the address has not been changed, after I was promised it will only take 48 hours. Changed it again, verified all my details. The mail never arrived. Phoned them again. Only to discover, they have send it to the wrong email address AFTER I HAVE VERIFIED IT THE FIRST TIME! Then the address was not changed, AGAIN!!!!!! Again I changed it, verified the email address and physical address again. Then I was promised they will send it within 24 hours. Guess what??? Phoned them again, asked to mail my statement. YES, THAT IS CORRECT, WRONG PHYSICAL ADDRESS YET AGAIN!!! So, I have requested it again, and I am still waiting to see my wrong physical address on my statement!!!! YOU ONLY HAD ONE TASK!!!
