Worse service ever

I took out a contract on the 09/07/2022 at the MTN branch in Bluroute Tokai.

I contacted the branch on the 12/07/2022 to inform them that I would like to terminate my contact as my financial circumstances has changed.

The email below is the advice I got from the consultant.

I contacted the MTN Customer service on the 12/07/2022 the consultant advise me I am within my right to return the device and the cooling off period is 7 days.

I went to the MTN store in promenade Mitchell’s plain where the consultant advised that I will not be able to return the device “ Because it does not work that way”.

I know I’m well within my right to cancel within the first 7 days.

I have sent MTN a formal email requesting to terminate my contract on the 12/07/2022.

However they still saying they are unable to assist me at branch level.
