Contract Upgrade

I had an upgrade due on MTN and Summer Mobile called to upgrade my account so I did the upgrade in August 2017 it is now 6 Feb 2018 and I have not yet received my device after I was told that They don't have the phone in stock I asked to Cancel the contract and be refunded up until today nothing.

when I ask to speak to an supervisor or manager they are always not in the office and on Lunch as per call center agent and they will leave a msg and they will call me back I have never received any phone call from them and I always have to do the follow up and call them endlessly this is very bad and unprofessional if I lived in Capetown where there building is I would of went there myself but I'm in JHB.

These people are useless and can't keep promises they make over the phone.

I think I should go see a lawyer and take them to court and make them pay everything maybe then will they catch a wake up. as this companies doors should be closed as they can't deliver.
