Phishing attempt warning Out of bundle data warning "MTN Mobi free spin"

This is a warning that there is a phishing attempt by someone posing as MTN. I have on three occasions received notifications from MTN that I am using out of bundle data. Click on this link to buy more data, or dial ****x*etc. On all of these occasions I have had more than 500 mb of data on my account. This is therefore an attempt at phishing. Further when my account gets credited with data or minutes from my contract I receive the following "Y'ello, Your Free Spins on MTN Spin'n Win expire at 23:59" There is no misleading conception that there is a free spin which will expire at 23:59. Once again, click on the link and there is no free spin. Rather you need to buy more to qualify for a spin. Clearly another attempt at phishing and getting you to enter your banking details into the link. Either that, or it is very misleading and clearly ********* marketing attempts which should be reported to the ASSA.
