Contract agreement not kept

I made a stupid mistake and agreed to open a Telkom router contract through Mondo mobile towards end of May. They failed to deliver on time which was a sign for me to just tell them right there and then that I don’t want to continue with them but I didn’t as I was giving them benefit of the doubt. Our agreement was that I pay R139 monthly for 10GB of data every month. I received my router 5 days before month end and when I asked if I’m gonna be charged the full amount and they told me Telkom will charge pro rata, guess what how much was that pro rata? A fat R262.78 end of June. Which means the amount they charged me for 5 days was R123.78 plus a R139 for the month of June. Which means I only got R16 off even though I didn’t use the data for a full month, when I called they said they don’t know how Telkom charge their pro rata, I should take it up with them. I didn’t do that because the contract I have was opened with Mondo not Telkom, they should be the ones doing that for me. End of July they didn’t deduct the R139 again, they took R158.03 and I don’t understand why.

These people are ripping us off for no reason, to top things up, it doesn’t even feel that they are putting that 10GB because it gets finished in less then two weeks. Before I took this contract I was buying 2GB for R139 on the monthly basis and it lasted me for more than a month, but now I pay more than R200 for data that lasts less than 2 weeks! That’s ridiculous.

I just want them to cancel my contract with them or else I’m taking this matter to ombudsman!!!!! Judging from the negative compliments about these people, it shows that their customer service is bad and they are not honest to their clients.
