ackermans northgate is a joke

i went to this store on the 24th of November to buy a cellphone, as a store that i trusted for years iam very and bitterly disappointed,i bought a cell phone on the 24th of november 2017 on the 14nth of december after work i got home took out the phone and charged it coz in my mind it was flat a few mins later i went to switch it on but it was filling with ink and getting blank, i called ackermans northgate and Samkelo answered the phone advised him of my issues, he said i must bring the phone i got there on the 15th and then i left the phone with them to sort it out later that day i was called by a manager called tshepo and he said they will take the phone for repairs and it will be ready in 21 working days i was upset that iw ont have a phone over the holidays but i said its fine book it in he advised he will call me back with details which he didnt, the 19th of january i was at the store to ask about the phoen i met samkelo again he said the phone went to repairs late because i didnt sign anything i told him no one told me, i called yesterday 29 of jan to ask about the progress on the phone but then tshepo told me that i would need to pay a fee for the phone to be a repaired and he is no repairer so he doesnt know how much it will cost to repair this phone and when my child cried in the background tshepo said that maybe i gave the phone to my baby and then my child broke the phone bacause now the phone has signs of negligence by me, and he is not a repairer but i need to come sign the terms sign the terms and conditions and pay a fee to repair the phone. the treatment i got from this store and their staff is very bad and i want my money or i want them to repair or replace that phone asap,they forced me to aggree that i was given the terms and conditions when i bought the phone but i remeber thembi just rica'red the phone and i paid and that was it. they are very unprofessional and rude, dont know how to tread people and tshepo didnt even know which phone is mine but started telling me about negligence as he says there are a few hicense phones that are there in their care for damage.
