Unhappy customer

Good day I am not happy with how woolworths has treated me, firstly I was wrongly accused of shop lifting, then they called the police and I was locked up and released 1:30 am with no transport to take us home, me and my wife. I was given a letter stating that I shouldn't even come near the store or enter the store, I did that but now I am receiving calls from debt collectors (Blake and associates) asking me when will I pay my account? I was puzzled because I was banned from the shop, I don't have a problem paying my account because I was paying my account before this " shop lifting story " The store never apologized for what happened, all of sudden my account is handed over. Why did they hand over my account, knowing that they have banned me the account holder from their store. I am scared to go to another woolworths because what if I will be embarrassed in front of other customers again. I want woolworths to tell me if they don't want me to purchase from anymore and who is going to pay those arrears that accumulated after they have banned me. I don't mind paying off the balance I had before they accused but not what accumulated after, I am sorry I won't pay that amount because I did not refuse to pay my account but the shop refused me to go in and pay. I am very angry with woolworths because this was the shop I trusted but they disappointed me as their customers. I also need a footage that shows that I was shop lifting. I need this matter to be sorted ASAP, it is destroying my name.
