Repair of phone

My phone was sent for repairs to fix a cracked screen. I went to collect my phone on Sunday the 4th of February 2018 at Hi store in somerset mall, where I made a payment of R500.00 (Excess fee). Thursday morning the 8th of February 2018 when i took out my phone of my pocket I saw the screen was cracked again, and I can promise you it did not fall again, as you can see. I immediately phone the store and the insurance, where i spoke to a Wilbur van Rhyne at Finrite. He advised me to fill in a claim form and explain exactly what happened. i was very dissappointed in the previous repair they did on my phone. Now Finrite wants to charge me again for excess fee. I feel that in the first place they should have given me a new phone. I am still waiting on them to collect my phone from the HI store, as they have promised to do so within 72 hours, that was yesterday.
