MTN THIEVING

Got myself MTN uncapped wifi with router at R249 PM after about 4mnths or so they started charging me R269 PM without any notification that the price would be going up until the last minute. They state they have a 100gb fair usage policy but every mnth without fail they start throttling me from the 22 till the 1st of the next mnth so essentially I'm paying more for less service TO THE POINT THAT I CANNOT EVEN GO PROPERLY ON SOCIAL MEDIA BECAUSE THE CUT IT DOWN TO 512 Kbps OR LESS. i'M REALLY DISSAPOINTED IN THE SERVICE! AND SINCE HAVE NOT GOTTEN AMNY FEEDBACK FROM THEM. Thievery at its worst, same like ESKOM paying more for less
