My number was ported without my consent!!!!!!

Sihle,a gentleman who answered call number 1 was of absolutely no assistance-had me on hold for 12 minutes and then transferred me to a Thembelihle,who had no idea of standing agreements with Afrihost and MTN-a supervisor who desperately needs product knowledge/training. My pre-paid number just stopped working and trying to load airtime resulted in errors informing me that i was not registered on the MTN network. When i called for the second time,already highly annoyed,another gentleman told me that my numbers been ported n to call the porting department immediately-this being at 17:50pm. Call them only to hear that they only work till 13:00 on a saturday. I then call back and speak to a female who though of some assistance requests that i get an afiidavit stating that i did not request the port,and then go to each service provider and query whether my number lies on their database. Infuriated to say the least, why the hell is this my problem now when MTN didnt bother trying to retain business by calling me to query or confirm the port? I now understand why MTN is losing clientele, why
