disgusting service

I'm truly disgusted with the service I have received from MTN<br> <br> MTN Clearwater branch has answered their store phone once since 8:55am this morning and told me to hold but they cut the call instead<br> <br> I went in.to do a Sim swap yesterday and I was notified that it will take 2hours to activate. This morning it still wasn't working so.I called the call center & they told me the Sim swap was never activated and is not on the system so I should go back to the store. <br> <br> This is an inconvenience as I went in for a service and expect it to be done correctly the 1st time. I couldn't go back to the store and should not need to, but no one is answering in order to sort out the mistake they make<br> <br> This is the worst service I've ever received
