NEW CONTRACT HASSLE

new contract hassle and not easy service as promised. I have received two quotations from Vodacom and trying to query amounts its a hassle to get any kind of assistance. I received the first quote on 27.07.2021 and second 30.07.2021 since then I have been trying to get an explanation as to what is going on and nothing. I am getting no help whatsoever. I was charged R120.00 which I have no knowledge of such amounts. The contract I agreed on is R449 but now there is another amount of R559 and totally different agreement all together. Agent that assisted me has since not responded to the query that I raised with him. I am ****en tired of calling Vodacom online ***4 number to hold for more than 10 mins then transferred to another number *** which will hold for more than 20 mins then they hang up. I want a resolution today this is ridiculous.
