Nonsense ETR error

I have been a customer for Telkom for almost 15 years and the treatment I received today was totally unexpected.i was In Telkom Waterfront Capetown and assisted by a white guy who totally lacks customer service and is an apparent ******

I was renewing my contract and taking latest Samsung s25 Ultra.He said it will come from warehouse on monday.i sent my husband to check up on them on Tuesday and he was told they just received it and will only dispatch later.When I arrived today,9th of April,I was told they have an ETR which they can't explain what exactly is it.I am totally appalled and want the manager to make contact urgently or else I am cancelling all my other contracts with Telkom.
