Nightmare created buy a schedule change

SA airlink sent me an email to notify me a of change of schedule... I called airlink to let them know that the 3h I had for my connecting flight now will no longer work. I can't say that airlink tried to do much to help me. Airlink offered for me to fly on a earlier flight which we would have been happy to take the only problem is that it was from Nelspruit not Hoedspruit so they couldn't even get departure destination right. My other offer was that I could fly out of skukuza but all expenses getting there would have been my problem. I did get a voucher to use within 2 years but not everyone has money lying around to pay for another flight. I had to get a transfer company to drop me at O R Tambo to catch my connecting flight to George. The only one who tried to help me at Airlink was a lovely lady by the name of Rulani. I will never use airlink again and I'm frequent flyer as I used them 3 x times a year from Tanzania to JHB. I did get an email from a scheduler who I felt was unprofessional and very short and needs training on being more helpful and professional.
