Unresolved Issue

Telkom Mobile wrongly blacklisted a mobile device of mine. That's fine, mistakes happen. I went into a store, and the consultant phoned someone, but said they couldn't help. I've been in contact with the @Telkom Twitter account 6 times in the last month, all apologizing for the delay but none doing anything more to assist me in resolving the issue other than saying a service consultant will be in contact with me or they'll investigate and get back to me. It surely can't take over a month to find this out?
