Telkom is de*****ing people

On the 22nd October I went to apply for data contract at Telkom which took about the whole day but to this day I'm still running around because I don't have a copy of the contract and the data that is given to me is totally different to what I signed up for,I signed for 40GB but I'm only getting 20GB for what price I don't know, coz when I was taking that contract it was aligned with my budget, when I go to ask for clarification they always tell me a different story and when I asked why there are no amounts on the debi check they say amounts are not important ,when I ask for my contact they always say their system is not working and when I say they should cancel it there's always a story to tell me. I feel like I'm being de*****ed by Telkom.
