MTN Home data dissatisfaction

MTN poor and pathetic service!!!!! Hi all i took out MTN home data for R250 a month the first instalment was R331 i paid it immediately no problems very excited to get wifi. When i got the rooter it didn’t work i went to MTN in standard bank building in joburg cbd where the staff lock the door and see you standing outside ignoring you flat i then knocked on the door as i took my lunch time to sort it out i am working and only get to di things on saturdays she didnt help me and told me to phone mtn so i did mtn then told me to go back and she has to fix the apn setting i went back and the lady said no my simcard in the rooter is not rica’d she then rica the simcard and told me that it should work now i went home after work very excited switched on the rooter it still didn’t work phoned again its the APN settings and i must go to the nearst mtn to my home which is east tand mall boksburg i could mot go during the week as i am working i watched a online video after 4 hours finally got it to work it worked for 6 days en switched off limit reached when i phoned mtn they telling me your acc is suspended you didnt pay im like what it hasnt even been a month yet and it was activates on the 4 of August we still in august no apprently there is an oustanding balance of R200 and something rand i then said well no i was not informed that i have to pay 500 and something rand for the first month and after that its 250 i tried to cancel they wont allow me to cancel and probably gonahand me over and ruin my credit score because their sales consultants doesnt know what they doing oh and i went to east rand mall how dare that lady tell me YOU PEOPLE buy stuff online now you want to come fight with us in store i was not fighting i tried to cancel because why would anyone pay R500 for something that only worked for 6 days i refuse to pay that amount its so sad mtn used to be the best i am so very disappointed and dont know what to do now i wasted petrol energy time and money
