Terrible customer service

Thought about taking a 24 month 500Gb Home WiFi contract with MTN.. I had a query regarding the router and contacted customer care. They were unable to answer a simple question and referred me to Sales. I phoned Sales who put me on hold and then cut me off. Went back to customer service who again referred me to Sales. I found the answer I wanted myself without any help from MTN and app**** online. A consultant phoned me and told me because I am retired I do not qualify. My guaranteed pension is R45,000 per month, I have no debts and there is no risk of being retrenched etc. In retrospect I am happy they declined as I will not have to deal with these unhelpful people again
