Wrong Contract Package

I responded to a promo about 2months ago regarding a 20GB anytime & 20GB night surfer for R145pm ×24mnths with Telkom, when the sales agent called to seal the deal I was informed the promo has further went down to R105pm and took the deal I waited for almost a month until I could hear from mobile store. Order confirmation letter was sent via email and eventually got my router a week ago(sim card did not have network) I tried to make contact with mobile store call centre they're agents were and still not available via the phone "due to covid19 social distancing", I made contact with telkom and I was informed the sim is not activated only mobile store could activate the sim. I sent emails almost every day and it was eventually activated however to my surprise with Telkom I was sold given the wrong package deal, Mobile stores decided to convert the package to a 5GB R80pm ×24months without my consent, I have been trying to remedy this with no luck, simcard has not been in use(I want the correct package that specified above), Telkom has informed me that I have 5 working days to sort the issue out with you before the new contract will be included on my billing statements...please sort the package issue out and provide me with the deal that I signed up for...Order no:MS-***6-1
