Incorrect Contract

I am extremely upset. On the first of November I went into a Vodacom store in Tygervalley to take out a new contract for my domestic worker. There was a special online for a Samsung J7 prime with 200 min, 200 sms and 500 mb data for around R300 or R330. I phoned the store beforehand and spoke to Bernadette who confirmed stock off the phone. I subsequently went into the store, took out the new contract and explicitly told her which one I wanted. I was concerned what would happen to the account once the minutes and data run out and she assured me that the bill would never go over the agreed price. I checked this with her 2 to 3 times. She subsequently printed the documentation, I signed and off we went. Now I find out the contract she chose is not the one I had requested and my domestic worker only gets R100 airtime loaded a month.

I have tried my utmost to speak to the consultants and managers in store to get the issue resolved, but they just refer me to the documenation and say "Sorry you signed". Well I am sorry, but the contract does not say "R100 airtime to be loaded". It has some other plan specific name. How am I suppose to know it's not what I requested, especially after having a detailed discussion with the salesperson?

I find it completely unacceptable that a salesperson makes a mistake and I need to now sit with the problem while Vodacom takes no responsibility. I expect that my contract be fixed. I have run into a brick wall at the store, but expect someone from the regional offices to get in contact with me! I have been a loyal customer for over 10 years!
