Misleading contract upgrade telemarketing.

I was called by a Pamela Nzuza in November 2025 offering a contract upgrade to my existing contract which was due for an upgrade. Explained what the contract entailed compare to my existing one and what the cost was (+-R448). What she offered was obviously more than that which I already had and cheaper than what my current deal had become. Secondly she assured me this deal was eligible to be used for Home internet and importantly that it can be used on the go on a pocket router. 3rdly The deal came inclusive of a home router. I signed up on the basis of all the above. But when I was invoiced I was charged a R576 Dec, R537 Jan, R575 Feb, R536 mar. which is absolutely not what I signed up for. The use of data on pocket router also proved a lie. Now I have lodged my complaint and dissatisfaction through Vodacom Customer care call centre since January I was told there was nothing that could be done and that I needed to contact a Vodacom rewards. I did contact these unprofessional people. They referred me to a store to obtain the transcript of the call and I did. I was vindicated by this call whch I have in my possession. Still they wouldn't help fix my issue. A need urgent recourse. Please assist
