Miladys exchange policy

I have shopped at Miladys on a couple of occasions in the past. On 17 September I bought clothing for more than R5000 at the Vaalmall branch. I live in Heilbron and cannot drive to Vaalmall during the week. On 26 September, at Bloemfontein Miladys I tried to exchange three tops for a larger size and return a casual suit which did not appeal to me anymore. I was informed that because I cut the tags off the garments they cannot authorize the exchange. Although I cut the tags of the garments, all the tags for everything I bought at Miladys that day was in the bag together with all the other tags of the garments which I kept and did not want to exchange. As you well know, Miladys is not the cheapest outlet and I have thus lost more than R2000 on garments I cannot wear. I find this exchange policy unfair as I had all the slips and the tags. If Miladys are of the opinion that the tags were removed, the garments worn and now an attempt to return the merchandise why would I want to exchange garments for a larger size if I was able to wear it in the first place!!!! This is unacceptable and has definitely changed my view of shopping at Miladys in the future.
