Lack of Service Delivery - appalling

Due to my minutes being depleted long before the close of the month I called Telkom's call center 3 weeks ago to seek advice, it was then suggested that I send a request in writing on a company letterhead to [Email Removed] which I did and received a case number ***8 and heard nothing from them since I called the call Center and spoke to Sandisile and Yushen Naidoo who both requested copies of the letter and said they will escalate the matter and get back to me-to date no update from either, how long does it take really, is this the best service that Telkom can offer their clients, I spoke to a consultant on Monday the the 28 December 2015 who gave me a different excuse that the contract can only be migrated on the last day of the month, it is now the 2nd January 2015 and still nothing, called the call center yesterday spoke to another unhelpful consultant and when I asked to speak to a manager he didn't bother speaking to me and asked the agent to inform me that tmbusitm is closed and I must call back today(2/1/16)-I didn't even bother as I am fed up-who else can I speak to at Telkom besides untrained call center agents who can't assist-please think twice b4 using Telkom
