Worst service ever

I went to Telkom workshop Durban on the 22nd last month,I wanted to do a sim swap since I was ****** previous day but they told me that they can't do it cz it's take them to credit vetting when they are trying to process a sim swap,they told me they will phone me but they didn't, I went there on Wednesday again,they said or it takes up to 7days, last week Wednesday I went to Telkom in Gateway, the guy gave me a sim card and said there is system error but that sim card will be working by Monday but still today it's not working and I don't even know what is the issue cz I'm doing a sim swap for a contract number. Must I move to Vodacom since I can't be helped by Telkom,I even sent them DM on Twitter but no response,what the use of social media consultant if you keep posting by don't reply to your DM's. I need this to be done asap or else I'm cancelling this stupid contract of yours, I've had it with you,I'm loosing money since I don't HV that sim card for almost 3weeks now, how are you gonna compensate me
