Waste of time

I opened a wifi account with Telkom on the 5th of September 2017 and was told I would be contacted by a technician with regards to installation. A week went by and I had received no call so I decided to call them to enquire. I called for the first time only to be put on hold for 25 mins until my airtime ran out. I bought more airtime and called again, this time I was only on hold for 10 mins. I spoke to an agent who informed me that a technician would be coming to install the line on the 14th of September. I took leave from work because Telkom cannot let you know when the technician will be arriving so we have to be available all day. when the 14th arrived I received 4 consecutive text messages stating that a technician will be coming to do the installation and that I must be available all day. I waited until 17:30 when I realised that it is pretty late and I had a suspicion that the technician would not be arriving. I decided to call the call centre to enquire. I spoke to an agent who told me that she cannot find my order number on the system. I could not believe what I was hearing because I spoke to an agent two days prior, confirming that the technician would be coming and I also received four text messages on the morning of the scheduled installation. The agent I spoke to could not help me because she cannot find the order number. I have consistently heard bad things about Telkom's service but I never thought it was this bad. The fact that you have no reference numbers for your calls shows your lack of accountability and responsibility to your customers . This level of unprofessionalism is sickening.
