Contract lost

Hi I was phoned by Shaun from Mondo on 20 January, who sold me a contract for a Telkom cell phone deal (Huawei P8L) . The process took quite some time and used up a lot of my time at work . He took my banking details, etc.The phone was to be delivered within 7-14 days. When I phoned Mondo's enquiry line today, Bavisha said she would return my call because there was no contract linked to my id number or existing cell number and she would try to look for it. She did not call back, and when i phoned again and spoke to another lady about it ( a pity I didn't get her name), I could hear this person knocking a pen on her desk in irritation as i asked her questions, with which she seemed extremely annoyed. She said that she could get someone to do a new contract with me; but i'm really not interested anymore, seeing that we started off on such a bad note. Also, one wonders if one signed another contract, whether the first one would appear out of the blue and one's bank account got debited twice.
