Requesting for my IMEI number

In 2014 and 2015 I purchased the cellphones (Which I was not aware that they are insured) and the amount that I was paying for those cellphones (included insurance fee). Both of the cellphones unfortunately got lost and I reported the matter at Foschini. I didn't receive the replacement phones from Foschini (as I was not aware that the amount that I was paying included the insurance) and they kept on charging the insurance until to date. I only found out in November 2020 that the lost phones were insured. Then I was given the contact details of the Foschini Financial Services and Customer Services. However, I haven't received any help until now. I feel like I am being ignored and being sent from pillar to post. I need my replacement phones or need to be refunded. I have contacted the Foschini Group call centre and on e-mail since last year, and they keep on telling me that they will get back to me. However, I am still waiting. All I need is the IMEI numbers for the cellphone so that I can be able to open a case with the SAPS and to claim for the lost phones.
