Unacceptable unprofessional service

am extremely Irate after visiting a cell c store of even date, I had gone in for a renewal,the following was asked 2 the consultant I am looking for a cheap option please can you give me my OPTIONS for mobile devices/ I was told about 2 phones only, I then assumed these must be the only two as I did ask for all cheaper options,I was not told about a discount which I'd receive for a sim swap a further consultant had to mention it the consultant then open the box , I did not touch nor tamper with the packaging or device,the consultant did not even hand me a brouchure to view my options, I then contacted a different store and queried if this was the best option for me, only to be told by a regretful consultant dat I was not given out MY OPTIONS as there were many more,I then called the store manager only to be put on hold for 20 mins and then had the call cut with no call back,all she said to me was the 7days does not apply and there is nothing she can do, there4 because of an unproffesional trainee consultant I am now forced to pay for a handset I do not want, I am not to touch the packaging for a further 10 days, this consultant is getting paid for a job to serve clients.
