Telkom - headache from hell

Have received the most atrocious service from Telkom Mobile, their many call centres and agents. I was contacted on Monday and offered a really good deal. I was informed previously that my contract was eligible for upgrade on 19/4/2018, so when I received the call I asked if this deal could be done as an upgrade. I was told yes but I would have to call 081183 as they were unable to do upgrades. I called and was referred to 081180 and then 10213. On each of these calls my upgrade date was confirmed as 19/4/2018 and my telkom dashboard reflects this as well. On calling 10213 I didnt even get to speak to an actual person just a recording telling my their records reflect I am not eligible for upgrade. I called 081180 and 081183 yet again (at great cost to myself) and yet again upgrade date was confirmed as 19/4/2018. An agent then suggested I call Cell Direct which I did, finally my upgrade was completed ... or so I thought. When I called to enquire as to delivery date due to long weekends / holidays they informed me there was no record of an upgrade being done. Told me to phone Mondo or Mobile Talk. AGAIN I phoned Telkom mobile, now they say my upgrade date is 19/5/2018 which in effect means I lose out on the deal I was offered. Website still reflects April upgrade date and I dont seem to be getting any joy or sense from Telkom agents. They seriously need to upgrade their service if they expect to be a player in the telecommunications game. I am absolutely horrified that a company such as Telkom can offer such inefficient and downright pathetic service.
