Worst service ever

I decided to order a product from home choice 23/01/2018 which they approved and asked me to upload my 3 month bank statement which I did. Even received an SMS that my order was approved. Days went by n I called the call center n was told I need to submit my I'd copy which I did immediately. Days went by again no package no communication and I called the call center n was told I had to submit proof of residents which I don't understand why I was told on the first call. Afterwards I made numerous calls and was told my order will be dispatched soon. Yesterday 15/02/2018 I called the call center again to find out about my order and spoke to Zikhona ref: ********** 73 and was told that all documents are received and my order should be dispatched before 22/02/2018. This morning I receive a call from home choice a lady confirming my details n told me that I need to resent my proof of residents again n just as I was asking her how long will I get my order she hanged up... Few hours later I get SMS informing me that i have to forward my documents to mydocs@ homechoice.co.za then 2 minutes after i get an sms that my order is declined. How do I get declined after I was told n received smses that my order was approved than wait 3 weeks after calling in and wasting my time,energy and airtime. Your service is pathetic
