Mondo Mobile misrepresentation of contract.

On Friday 18 October 2019 a lady from Mondo Mobile called me and offered me a better deal on my Vodacom cellphone contract. Two or three times she said that "You get to keep you old number". I would NOT have been interested if a new contract meant changing my number. I was interested because I run out of data by the 15the of each month, and she offered me 10 Gigs of data - not ONCE, not ONCE did she mention the word 'once-off'. The offer was 390 minutes and 10 Gig of data. I agreed and the simcard was delivered by Ram Couriers on Wednesday 23rd October. By the next week I still hadn't signed a contract or anything, and on Tuesday 29th October I called Vodacom in an effort to find out more about the 'upgrading' of my contract, as I understood it to be. The very friendly lady at Vodacom told me that it was in fact a NEW contract with a NEW number (the package containing the new simcard is still sealed) and that the "fantastic" offer of 10 Gig was, in fact, ONCE-OFF. I use about 2 gig of data per month, so what use will 10 gig be over a 24 month contract? She then put me through to Ashton from Mondo Mobile, and I explained to him that I do NOT need another contract. He then tried to offer me another option - TWICE. What part of I do not need another contract/do not want/cannot afford another contract can't these people understand? It was still within the fourteen days cool-off period. My reference number 36096 was given to me and Ashton promised that somebody would call me within three working days. Wednesday, Thursday, Friday. Nobody called. I checked my Vodacom app last night - the new number still shows on the app, and my talktime balance is now R780.00 - in other words, TWO month's airtime. I want that contract removed from my name, with NO charges. Immediately. Alta Roux
