Edgars Northgate need to get more competent staff

I bought 2 jeans for my son in Edgars Northgate on 23rd November 2018. On the Monday 26th November 2018 I took the jeans back for alterations. The guy that alters pants was right there and said he will do it in front of Mpho. He asked me to come in on Wednesday to pick up. I told him i will come today. I go there pick the pants up paid for my account in full because on that Friday Mpho put it on my acc and came home. I get home and tell my son to try it to my dismay no alterations was done. I take the jeans back to Edgars they tell me a staff called and told me they dont alter at the waist. Edgars please do an itemized billing cos no one called me and your staff did not want to believe me. Then i asked for a full refund on the jeans on my card which again Edgars could not do nor did they want to give me cash. Not forgetting on Friday they asked me twice for my cash sale slip and I put it in the packet which they took. Today they tell me they dont take customers slips. I used to love to shop at Edgar's Northgate but after today never again. The rest of the clothes that I bought on that day I will go back and return and therafter I am going to close my Edgars account. Today I felt like Edgars Northgate made me a ****.
