Extremely bad service from Avios credit card

Sabc 3 morning show promoted avoid rewards which I will benefit from a a frequent flyer. So I thought that I should take advantage of credit card opportunity. My bad experience started when a african make called to confirm whether I have absa accounts he literally interrogated me like immigration or police officer. Since beginning of December 2015 I've app**** for this credit card but had no joy. When u call the call centre on *** no one answers and you wait between 20 25 minutes and still get no service. Today a Neledi answers after I waited for 20 minutes and when she couldn't answer my question she hung up cut the call. I've never came across such bad service. I feel I have beg avois to give them business. I've sent all the required docs to [Email Removed] &amp
