Cell phone sim swop disaster with Edgars cellphone contract

My cellphone was ****** on the 1st of September 2022. I got a new one on the 3rd. I went to the vodashop to do a sim swop. The said the cannot do it, the phone sim was a Blue Label connect contract from Edgars. I called Edgars. They said the cant change it. I can buy a contract sim and do a sim swop after 2 days. Then they can do a migration from a contract sim to a prepaid after 14 days. After 2 days I called and nothing was done by Edgars. Not a sms or call to say that they are working on it. After many calls and airtime and 2 weeks later nothing has been done. The people who take your calls are very polite, but after the call and many promises nothing happens. I want to keep my number - but I can do nothing before the sim swop has not been done.
