Pleading for REFUND

Requested the refund after I booked collection for 3 days and they kept on promising they will collect ..collect. On the 3rd day I was told the driver was there and could'nt find me, funny enough the cell number appears on my waybill, so why did the driver call me as I have been waiting till 17:00 everyday for them to come collect. Then I requested another courier to pick up as the parcel was very urgent. Then I requested for my refund. Guess what from the 06th December up until now I am still calling and emailing but nothing is happening. The call center ladies won't put you through to the accounts department, then you tell your story and they will discuss it internally and they will come back with an extended promising date feedback, and when that day comes, no one answers the phone. This is the ****iest company ever.
