Pathetic service

I bought a Wifi router online and paid for it cash. When I got it after a short period the router was branded with Vodacom Not Hauwai as advertised, I tried a different sim card which confirmed the router was locked. I reported it and explained why I didnt take a contract as I wanted to use another provider. I logged a request for collection and refund as it did not suit my needs . First it took vodacom consultants an hour to figure out that the device was cash and not contract . When I got to speak to someone they confirmed collection withinn 3 - 5 days after 3 days I followed up and was told that the request for collection ad refund was cancelled a few minutes after I spoke to someone at Vodacom . This speaks to the reason why I dont want any services with Vodacom cause the service is rediculous . I requested to speak to manager and I was denied that so hopefully this way I can access someone to help me with my requrst
