Complaint

My package arrived on the 29 of October 2015 from hong kong. The following day I received a call saying i needed to fill in a clearance form which i didnt know how to so i called on the 2nd of November for assistance which they did and i submited. Then i recieved a quotation saying i needed to pay R525.60 and i gadly paid then i got an email saying they recieved my payment but i needed to pay R690.14 which my invoice didnt say R690.14 so i quered that to no reply. I have been calling and no one picks up only to find that Mpho is on leave and my package is no where to be seen. Why would Mpho help me then after that when she goes on leave my package dissapears and they tell me my waybill number i was given by them doesnt exsist.
