Brain dead Vodacom

No feedback after almost 3weeks. all vodacom had to do as per signed agreement is to send their router per courier to connect to fibre line installed. according to their records, our router was delivered to another client. they will ensure we get ours within 48hours. call logged. a week passes, no router, phoned vodacom, they are not even aware of the first call as NOTHING was logged by the agent. log call again and special request for someone with half a brain to contact me. never contacted. another 7days, vodacom system shows our router was delivered, no mention of previous logged calls, phoned corporate office. spoke to some guy that sounds half awake and with some schooling background, he promises to sort the same out and to follow up with a call back. well dear vodacom, my monthly installment to you is r2000. 00. please inform me how you would like me to proceed in assisting you, to deliver the router so that YOU dear vodacom can charge me an additional r800pm. do you want, need bussiness? can i request that anyone, your director or anyone that has passed their matric exams with atleast 40 percent contact me and confirm a delivery date of the router i need to have so that we can continue living our lives with normality? . how difficult can this be?
