Useless deaf agents

I had made a purchase on the 06th Feb 2018 and the next day requested cancellation. However the package was already shipped on the 07th February and out on delivery on the 09th February. I have informed all consultants that i urgently need the funds back into my bank account which they confirmed once the package is retuned to warehouse i will have my money into my account. Today is the 16th February 10 days later i call back and mickayla the agent informed me i need to provide my bank details this has ****ed me off all this time they could have informed me they needed my bank details which i would have provided them with. I had asked to please put me through to the manager Kevin came on the line and acted as if he cant hear me and cuts the call!! I called back and spoke to Chadd who kept telling me he understands me which is kind of funny because they didnt UNDERSTAND ME when i asked for my REFUND TO BE PUT BACK INTO MY BANK ACCOUNT!!! I have so may reversed debits on my account and each RD is R150 which i need to pay back because of their stupidity i need to pay the RD on my bank account i request an instant payment in my account and a refund for all my RD on my account as i should not be responsible for it as your agents did not advise me correctly!!!
