Bad service from customer care for past 6 days

I have been struggling to get a sim swap done for the last 6 days. I requested it on Friday and was told someone will phone me back. they phoned back and I was unavailable at the time. nobody told me they phoned. on saterday I phoned and was told they will resend an email and they do not work on holidays and sundays. <br> <br> On Monday I phoned and was told again that the email will be send someone will phone me back and I gave alternative nrs. Tuesday I was told the email will be marked urgent as I started getting upset and I asked for a ref nr . Wednesday I was told the ref does not exist and I complaint and was told that an email will be send to the team leaders and one of them will give me feedback during the day.. no call received again. Today ( Thursday) I get told swap is finished. I entered the sim and it is not working. <br> On phoning back the customer care I am told the case was closed because they phoned me on Friday and couldn't get hold of me.now the supervisor will call me today and do the swop. they are just wasting my time.<br> 6 days and everytime its a different story... if this continue I will cancel my contract and go to another service provider. it is disgusting service
