Very slow response.

Due to unforeseen circumstances I was unable to pay my telkom mobile account and my sim was blocked. I am at fualt for not paying on time and I take full responsibility for that. My issue is that I have now made a cash deposit including an additional fee and am told that it will take 48 working hours before my sim will be unblocked. I have also payed a Cell C account that was blocked and it was unblocked in 5 minutes. Why can they not resolve this in a matter of minutes. I have my proof of payment. If I could be put through to someone that could actually help me it would be fantastic. I have now paid and my money is in thier bank account. It is unacceptable that I now have to wait .
