Pushing for sale on contract with wrong devices

They have a special on their website for s24+ including watch 6 Classic LTE that comes in 43MM and 47MM. I app**** for it and got a call from the agent this morning. This agent pushed me just to agree, she didnt even ask what contract i wanted and then told me im getting the 40mm watch which is a totally different watch, i told her i want the 47mm classic as on the website, she said they dont have, and then i told her i dont want to go forward and she put the phone down. she also told me the debit order will be for the max and not just the R999, all she wanted to do was just push me to sign, this is disgusting MTN, stop using call centres like that, im even thinking of changing to vodacom
