bad service.

I went into mtn clearwater(not the one but the food court).i went in as my phone was ****** and i required a sim swop.All is well and the sim swap was done however i am on contract and i requested that my bis be activated per month, i was then told that i need to call 808 to get this activated and i am very annoyed as the 808 number works but as soon as i request to speak to a consultant it cuts me off, i have now gone into mtn over 5 times and this is unacceptable!!!! i mean how difficult is it?????.i want this to be sorted out today or i am cancelling my contract with mtn and i will take my business else where, as the service is HORRIFIC.I am now fed up as both clearwater mtn contact numbers are always engaged and i cant keep going in and getting nothing sorted!i dont know why the phones are always engaged and never work as i have been calling for the past 3 days and it never works.
