Ive been waiting a week to get my sms issue sorted

Ive discovered that im not receiving or able to send out any sms messages, after making a purchase from my internet banking, upon not receiving sms confirmation of the purchase i called my bank and everything seemed to be fine the purchase was successful. i than contacted my service provider to find out what the problem is, after calling various agents as well as the technical team i was told customer care is suppose to resolve this. an agent told me that this case was logged, and that a rep from cellc will call me in 48hours and the case will be resolved. they havent called and then i followed up myself today. just to find out that this case was never logged and that i know have to wait another 48hours. Ive always been with CellC AND HAD NO ISSUES BUT NOW I WOULDN'T RECOMMEND THIS SERVICE PROVIDER TO ANYONE. They cant tell me anything and keep giving me the run around im so frustrated and irritated by the *********** staff.
