Telkom Service - Bad

I am a frustrated Telkom client. I have been receiving countless calls from Telkom representatives regarding renewing my contract , when I finally visit Telkom Hatfield store the assistant helps, all I requested was for the contract to be identical to the previous one or the one that had ended (I specifically asked for the deal to remain the same 10GB night , 10GB day , R139 pm and *TOP UP* option..The consultant put me on an open contract, meaning the data doesn’t get depleted according to the meaning of ‘open’ however I have been topping up my data since the upgrade, until last week when I couldn’t as I got an error saying I am not on a smart broadband plan..I checked with Telkom Hatfield , I was told they can’t change before 3 months of renewing the contract, after minutes of complaining they make a call and suddenly they are able to change to top up..
