whjere dstv and mtn meets biggest **** ever

i am very disappointed with dstv and their dstv internet seem like they did not actually knew what they where doing, i have bought the dstv internet and their router last month in march, ever since the router arrive I've struggle to connect the internet, i called them numerous times the consultants seemed clueless because each and every one i spoke to came up with different story, worst is they don't even call back, you have to use your airtime and hold for very long them, i have recently sent email to their help desk because i want to cancel the contract and i want my money back, they have not rep**** back, i then called again with my airtime asking for cancellation and refund, i was told i now have to wait until they come and collect their router before i could get my refund, i think dstv is been unprofessional and **** because should i have not paid for their router i was not gonna be able to use the internet, i took so many initiatives they did not do ****, i just want my money back they can come and collect their router please that's all i am asking for, it has been almost 2 months now since is ii had it and its useless,
