Overpricing and Non-compliance to CPA & Communications Regulations

I took over an uncapped contract from my daughter when they moved out. The contract package was then down-graded to 20GB capped @ R349 p/m. When I was investigating on upgrading again, I saw on the internet that the costs for the 20GB capped is R199. On querying this, I was told my account has been adjusted. I further queried when did this change, as I am on a month to month contract not a fixed term/priced contract. Waited a few days for a reply, only to be told that WIRUlink can change their prices when they want, without notifying clients. This is a direct contradiction to both the Consumer protection act & ICASA Regulations. To me this show a total disregard for their clients and Legal rights from Wirulink. 26/09/2018 Just got an email that read, management confirmed, we are not obliged to inform existing client's of any price changes.5
