BIS Paid but not connected

My husbands BIS on his blackberry expired. He got funds and renewed his subscription on 2 October. He received confirmation sms, but he still can't use the phone. Neither his BBM, Whatsapp,emails,facebook or browser is working. He phoned telkom on many occasssions and everyone is telling him another story. The last person promised that it would be sorted out within 72 hours, and that promise was made on the morning of 6 October. That is unacceptable. My son is also battling with Telkom - what is going on with this company and its bad service to customers?
