Terrible customer service

I had an account with foschini which upon my request of closing the account was informed I had cellphone insurance which I was not aware of nor did I sign up for it . Foschini informed me to contact finrite what a complete nightmare . Firstly they agreed they had no paper work for the insurance and was informed I would receive my refund for the past 49 months . The agent I spoke to was Kutlwano Mutle ,upon my second follow up I spoke to Nompumelelo Zitha who confirmed it will be credited back into my foschini account with 5 working days , my third follow up spoke to Siphiwe Marobela who said all of a sudden there was no information of the refund and will speak to team leader and will call be me back nobody phones me back . Again I call they can never put you through to the person you spoke to , their lines are so bad as if it's not a legit company this lady who picks up the call was very rude and when I insisted on speaking to the team leader she put me on hold and hung up after saying "oh my God". Finrite must refund what is due to me and stop sending me from pillar to post with agents and team leaders that give terrible service and you cannot even hear them probably .
