cellc incompetence

Last week Sunday did a sim swap just after 2pm. The consultant said to me wait till around 8pm before inserting the new sim. At 5pm evening my original sim stopped working so I thought it's the process of the sim swap. At 8pm that night I inserted the new sim but nothing happened. No network or anything. The next day I called Cell C and they mentioned the sim swap showed successful on their side and if the sim is not working I need to do another sim using a new sim card. So I don't have time during the week as I work so I went to a cell c store today and bought another sim. I had to call twice because I wasn't receiving the otp number (last week I used the same number and I received the otp immediately) third time I called in to do the process again only to be told the number I am attempting to do a sim swap on has been blocked due to the excessive attempts and i need to wait for 24 hours before attempting again. Now just to let you know Cell c I need my data I am paying you for my line of work. I lost a complete week of not being able to access my data due to this incompetence. Definitely will be migrating at the end of this contract!!!
