Cellphone insurance

My phone was ****** in April 2017 and was paid out and I went to to Edgars to get a replacement phone. Since April i have been billed for the insurance on the ****** phone as well as the new phone up until October 2017. I was told to speak to Finrite, they cancelled the duplicate insurance and advised that they have refunded my Edgars account on the 27th October 2017. I have been advised by Edgars that this has not been done. Finrite has insured me that they have done their part. I have been promised to be contacted by a manager and then a customer service agent to help resolve this but to date have not received the call back and everytime I call I get put on hold for 15 minutes and still no manager is available to speak to me. I have done everything from my side with no assistance from Edgars. Can someone please help resolve this issue already as this is extremely annoying that I have to call and try and resolve an issue that is not even any fault of mine. The mere fact that no one at Edgars is prepared to call Finrite to help get down to the bottom of this is pathetic!!!
