Telkom
After many years I cancelled my Telkom account mainly due to issues with my landline being out of service, interruption of internet service etc.  My frustration is that I have more than R15,000 credit on my account which Telkom has yet to refund.  Every time I contact them (whether this is via email, phone call or a visit to their store at the Mall of the North) I receive a new reference number and the process seems to start all over.  According to the customer service representative at their store my "case" has been closed since June, yet I am still waiting for the money to be deposited into my account.  The account details and supporting documentation I have submitted on three separate occasions.  During my last visit to their store the customer service representative suggested that he request a call back from Telkom to avoid a new "case" being opened.  They did phone me back, but after putting me on hold for one hour 2.36 seconds I dropped the call as it was evident that they were not going to answer my query.  This is exceptionally poor service and I find that holding my money hostage in these financially trying times is completely unacceptable.
