Delay in credit limit increase.

Two weeks ago i called Mr Price contact centre to query my Mr Price account that was closed more than 3 years ago. I've always received statements saying that i had a credit of R1 because i paid R1 over when i closed my account. Wanting to reinstate my account, the consultant on the phone told me that the account was still active i needed to go into the store to get a replacement card - which i then did. The consultant on the phone advised me that my credit increase will take place on the 7th of every month . I have waited one week for the sms which will advise on my credit limit - which is currently R1. When i called in to query this delay the consultant on the phone advised me that they are awaiting my ITC check because they need to increase my limit. Note: when i went into the store to collect my replacement card i was advised by the teller that the check will take 3 days. . I then checked my own credit score thinking that i could have a negative scoring hence the delay however i have a credit score of 676/706. What is the delay?
