Disgusting service from Edgars Mall of Africa

I am so disgusted by Edgar specifically mall of Africa branch. I bought shoes in July because I had forgotten my formal shoes and had a meeting with my client. I wore them twice, the day of the meeting and 2 weeks ago when they broke the heel. So literally I wore them once as the 2nd time they got broken

I took them to the shop where they requested the receipt and I don't have it, luckily I have the bank statement with the transaction details. The Store manager by the name of Koketso have the worst attitude I have ever seen in my entire existence and told me the shoes have 3 months guarantee or else there's nothing he can do. How should one smell that the shoes are gonna break and wear them for the 3 months in order to meet the terms and conditions. I bought the shoes for R300 only to wear them once.

I am beyond disgusted with Edgars and have trusted them with their quality but I have learned my lesson and will make sure I spread the word to everyone to be aware of how they treat their customers.
