buy and get service is pathetic

Buy and Get sms'ed me that they had booked the 06-08 February and I should send them a delivery address for my vouchers to be couriered to me. I responded to the sms a day after it was sent to me, which was the 29/01/2016. The week after I called buy and get and after waiting a while to speak to someone, a lady by the name of Liezel answered to check why my voucher was not couriered to me. She said she call me back after half an hour. she did not call back. I called buy and get the following day and after waiting a while again to speak to someone, Liezel said they are still checking. she then said i will get my vouchers on Friday, Friday after 2 i called spoke to a consultant and Lee, they advised me that they will deliver to my home after 8 pm ! Lee then called me on Sat the 06/02 and advised me that the courier came to my home at 10:30 pm and they dropped the voucher off at Protea hotel. I refused as it was late notice. i wanted to book my 2nd option for the 13-15 feb. it is now Wednesday and buy and get did not contact me to confirm my weekend at Protea hotel. SAMSUNG'S BUY AND GET CAUSED ME NOTHING BUT INCONVENIENCE AND A HIGH PHONE BILL!!!
