Very Unhappy Customer

This complaint is regarding FNB reconnect. I recently took a contract and Wow it even came with 500MB free data only to find out that i selected to do a top up once that was over but i was being charged out of bundle rates. How can you give a free offer and then say you will pay once your free deal is over , it makes no sense. Your staff are not s****ed enough , i had to make over 5 calls to get a simple answer. How is it that your customers are not informed about wanting this so called free data capped once the 500mb are over? Well i should have seen this coming because the staff don't have much product knowledge hence i had to make so many calls. I expect my refund for the amount i was charge due to being misled about your free modem. Had i been made aware by your call centre agents i would have immediately told them to have this capped and that's the reason why i even chose top-up. This is an absolute ******* and if this is not resolved soon , i will take this further with consumer watch.
