***** at foschini and finrite

I bought a cellphone on my foschini account in beginning 2017 on a 6 months payment plan. After a few months I discovered my account balance is increasing in spite of me paying monthly payments. I took them 3 more months to figure out that they have changed my account to a 12 month period resulting in them charging interest, plus they added a magazine that I never requested but had to pay for as well as insurance I did not request. I have tried over and over to cancel this & have it changed back to my usual 6 months & get the money back that they wrongly took from me but to no avail. I have phoned Finrite & go to speak in the Foschini shops for more than 6 months plus sent emails with NO RESPONSE. They keep taking money from me. I cannot wait to close my account and be rid of Foschini for good. An appalling terrible terrible ******** service !!
