Cellc disclosure

Good day, I recently took out a contract with cellc and be a loyal customer, however the agent did not disclose the the out bundle amount to me. Which was R220 and is a lot of money, Resulting in my bill been very high. I did request a call recording but no manager was on site. Very poor behaviour for cellc and the agent. I hope they can resolve this. I did do a data top up twice but was still lot aware of out of bundle charge amount.
