Neotel N1 city worst service ever and Wifi router hardly ever active!!!

I have a Wifi router that is hardly ever active, I go into the store numerous times to complain about it and I am continuously told that a technician will come out and check the coverage, the last time I have been there was on Friday the 29th April 2016, I was assisted by chantelle, she assisted me and said that she would call me to find out if this has been resolved since today I havent recieved a call from her, she was actually the most helpful than any other consultants. Russell has dealt with this application never has he done his job properly I had to wait nearly a week in order for device to be active after collection. I have endless problems with him as well as a new consultant Ero Leigh that recently started there that constantly makes rude remarks and laughs whenever I enter the store because of a problem I have had before with Russell, Ero Leigh or Russell are customer orientated whenever I walk in there I feel like not being in store, because of these two consultants, (Russell and the Ero Lee) however I am glad that I got some kind of help from Chantal. I am disgusted by this why should I drive all the way to Durbanville for proper service when N1 city is the nearest for me as I do my weekly shopping there, not only have I recieved pathetic service from this store, But I am also paying for a device that is hardly ever active and if it is speed is slow and connection drops all the time. I am waiting on a technician to come out and asses this as soon as possible, you deduct money every month for a device that hardly ever works. I do not think this new consultant Ero Leigh know's how to do her job properly I have a seperate account for my telephone account I went to her to settle account and change to prepaid on Friday the 27th April 2016, She did not know what to do and ended up having to go to Chantal for help, She has a smug look on her face whenever me and my daughter enter the store yet she cannot do her job properly!!!!!!
