no network and sim swop problems

Good day <br> i recently reported to you guys that i have not had network on my phone since Thursday evening and and then the response i got was that my sim card could be faulty and i should purchase a new sim card and do a sim swap . i then did exactly that and called your customer care centre and gave them my details and then THEY TELL ME THE DETAILS I GAVE WERE WRONG AND THE SIM SWOP COULD NOT BE DONE AFTER THE THIRD TIME I HAVE TRIED . I AM NOT PLEASED WITH THE SERVICE AT ALL AND I AM CONSIDERING CHANGING MY NETWORK . THIS IS VERY UNACCEPTABLE BECAUSE I CAN NOT MAKE AN CALLS AND ITS AN INCONVENIENCE TO ME.
