NeoFlex MIFI

On 26 of March 2016 I bought Prepaid Wi Fi Moderm and R49 Data, when I reached home I plugged it in and was not connecting to the Internet .I took it back and Sim card changed and purchased Data and was given to me that it was connecting,at home it was not connecting. Took it to my friend who got the same moderm it still was connecting. Thinking that maybe there was no Data I bought Data at PNP still not working. Took it back to Neotel Midrand on the 7th April 2016 and I was promised that as soon as it has been working they will phone me,nobody phoned. Today(11/04/2016) I went there to check on progress since there was no communication was informed that that type of moderms most are not working it was testified by another customer with similar problem like mine. Seeing no progress I requested refund but was told that there is no refund on Data I purchased totalling R200,what I need is the Data money spent and false adverts on the products they sell which are not working. It is ******* to sell products which are not working so that you can money on data whilst testing the connectivity.
