Disgusting customer service at MTN

I bought my contract R499 ZTE router this year at Feb, to my surprise in May it didn’t want to switch on. My first complaints is towards MTN Jabulani Mall Soweto, i took it there on 1stJune around 10 and a mature lady with fair skin colour told me they don’t take appliances bought online and i must take it to MTN 14th avenue . I mean what nonsense is that is like MR price telling me i must fly to cape town to return what I bought online. I went to Maponya mall same day and i was helped , why did Jabulani mall didn’t wanna help. Now i go to Maponya mall on 10th to ask for a collection number as technical department needs it, to my surprise my router is still at Maponya mall, Jabulani Mabuza decided that im not important and set it aside as i dont matter to him right. Pertunia the manager promised that it will be collected yesterday guess what its still in Maponya mall. Wow is this how paying MTN client are treated, its really disgusting. I want my home router fixed as in yesterday as my family is sitting without data to work and do school projects. Please contact me with a way forward ***.
