Phone sent in for repairs on 5 December 2015

I went to the vodacom brits mall branch on the 5th Dec 2015 to sent my phone (Blackberry Z3) for repairs for a cracked screen as i have an insurance on the phone, had an insurance form filled out and signed of which i still have a copy. <br> I recieved no feedback or communicationfrom anyone from vodacom/ the store, thus on the second week of January 2016 i went to the store to check my phone, only to find that the phone was never repaired and i was never advised. on enquiry i found out that the insurance form was not submitted with the claim, i ask the store bto investigate and resend the phone for repairs.<br> <br> Again i got no correspondence from the sore, on Monday the 25 Jan 2016 i went back to the store to enquire and again i find phone hasnt been repaired and i'm asked to fill in another insurance form which i didnt agree to because i had no explanation to what happened to the claim form which i filled on the 5 Dec 2015. Again i asked for thourgh investigation and to be updated the latest end of business today but havent had any feedback.<br> <br> i'm at my wist end please help urgently
