Blacklisted phone/wrong billing/No service

On 8/12/2015 someone called in and blacklisted my phone.Telkom accept the call and blacklisted my phone without my consent.We reported this to the Tygervalley branch and until today month later nothing has been sorted, I'm paying for a handset that doesn't work and is lying with the branch.They did numerous swim swops but when my sim is in my own phone the phone don't want to work.But when the sim is in another phone is suddenly works.I logged a few emails but nobody is coming back to me.I want either to cancel my contract or give me a new phone.My contract is only 2months old and I didn't blacklist is. The other problem I'm having is that my tablet contract is finish after 2 years and need to go over to the R99 bundle as confirmed by the branch but end of Jan my account will be debited with R700 which is unacceptable as that is incorrect. I urgently need somebody to have a look into this as this is really unacceptable to just black list a phone if someone call is its ***** and breach of contract. If I don't get an answer as soon as possible I will have to cancel my debit order because I'm paying for stuff that I don't have use of or accounts that's incorrect.Telkom is *****ing!!!!
