Battling since Sunday to do a Sim swap

I was in Canal walk on Sunday to do an upgrade after already waiting for about an hour in the queue. I was helped by a friendly gentleman but upon doing the sim swap when we received the sms to reply yes to, we got a message that the network is out of order. He told us to give it time and keep trying. I tried all day and went back th evening. Stood in a long queue again. Helped by a lady this time,she put a message through to whoever and told us it will be sorted .Yesterday evening I went back still unsatisfied. Again in a long queue. I was helped by Jean-Lee. He also assured me that all will be sorted. Another day later I am still not able to use my phone. They also activated 30 gigs of data to my old sim which I can't even use which will expire in less than a month. I would like to just cancel the contract as I realise that I am dealing with *********** people. I have never received such horrible service. People need to know as the service in this country gets worse everyday because nobody does anything about it. If it's not sorted today I'm going to cancel. <br> <br> Kind regards,<br> Kieyaam Bantom<br> ***
