Poor service and suspected theft.

On 8 August 2021 I bought a black tracksuit pants at the new Mr Price Sport branch at Langeberg mall in Jeffreys Bay. The pants was to small and return it to the store the next day. The manager, Rose, offered to check if there were my size available at the Baywest mall in Port Elizabeth. She confirmed that they had stock and gave me a card with the details of my order. No cash or credit on my credit card or slip were given to me. I presumed that it indicated that I paid for it and can only collect it from Baywest mall. To my surprice they informed me that I should again pay for it. I at first refused and they phoned Rose who stated that a credit was made to my credit card. I said that I will double check and as I suspected no refund were given. What happened to my money? Another insident happened during this time. I bought a red shirt for my son on the 7th of August 202 at the Langeberg mall. I returned a different shirt which was torn to the store the next day. They took the slip as I was happy with the sizes and everything appeared fine with the other clothes I bought.However after one wash the red shirt had a torn seam. I try to return it to the Baywest Mall who blatently refuse to exchanged it, because I didn't have a slip. Please note as previously stated, Langeberg mall took the slip when I exchanged a different shirt, which was also torn. I bought more than R2000 worth off clothes over two days and this is the thank you I get. This service is suspicious and extremely disappointing.
