Bad service

I place an order at Take a lot and I choose COD for payment option. I received a error message that the option is not available I must take another option. I choose debit order option and I paid the goods and services on the same time. I received an email from Take a lot that they received payment. Received a call on Friday to collect the order and I was advised that I must pay to received the goods, I told the driver that I paid already and I even showed him the proof that I was told to go and communicate to the person I spoke to the first time when I placed the order. like really caused I order online. On that day called the call center and advised them about the problem. I spoke to Kwanele Nonxeba and he promised that he will change the payment option and advise however that I already paid for the goods via debit order option and I will received the goods on Monday before 12h00 pm. Monday I received a call again from Take a lot about the order and I must come and collect. Sign for the order and when the driver supposed to hand over the goods he told me that I must pay the amount, told him that I paid already and I ask him the order number it was totally different to the one that I was expecting. Told the driver what happened on Friday and showed him the order number that I was expecting from Take a lot and the SMS that I received. So the driver was worried that I sign the order already and im not going to give him the money for it caused that paid it already from day one. The driver didn't give the order and he left. Received an email about the order that I was expecting and they say that it was delivered to me. Thinking that it is the order that I sign for in the morning but with the different number but still that order said COD not paid for it as they promised that they are going to fix it. Take a lot system started this whole confusion, I paid for the goods but I was told to pay again 2. the call center fail to deliver the promise as they advised that they will fix the whole issue (payment option) but still it not sorted 3 sign the goods that I received it and received an email that goods were delivered but knowing for sure that I didn't received anything from Take a lot till to date.
