Bad service

I received a call from mobile talk stating that they are calling on behalf of telkom to offer me and lte upgrade. I proceeded and was given numbers to calm the Raheesa if I had any further queries. I tried call back as I had a question and when I called telkom they told me there was no such person on their system. I then called the second number she had provided me with which went to mobile talk . The consultant who took my call said that Raheesa was in sales and sales do not take inbound calls. So I requested that my application be cancelled which I am told was escalated for cancellation. All I want is for someone to contact me and confirm that my application has been cancelled
