Terrible Service and lack of communication

Very disappoint once again at Vodacom's service in resolving my issue. I completed the required form to unblacklist my phone and followed their procedure of switching of the phone for 24 hours. They told me that my phone was unblacklisted on email and when I went to check at a Vodacom branch, they advised me that my phone was NOT unblacklisted. This is unacceptable and bad service. They have ignored me and unresolved my issue.
