Shocked at Vodacom

Absolutely shocked that i signed up for a fibre contract in march 2021, still no fibre in August, and then when i see an advert for prices cheaper from vodacom thinking my prices will be dropped to suit, i have been told that the prices cannot be changed and i should rather cancel or accept the terms. Seems like its normal business to rob customers due to the fact that it takes forever to get anything done at Vodacom.
