Useless Service Provider

Poor and shocking customer service. From receiving my SIM card on Thursday the 3rd till today I cannot seem to get my sim activated. Telkom has advised that I will be charged a prorater amount on the line once it is active however when I go into the store to do a sim swap they cannot do anything as the online sales department has activated the contract yet cannot seem to rica my sim. Every time I call in the time frame gets extended to a longer period of time yet I will be charged almost a full month according to their system saying that is up and running. Please advise how the biggest service provider in the country can be as pathetic as what they are? How long does it actually take to get a sim to work because apparently 72 hours later now quantifies another period of 72 hours.
