I was disrespected and embarrassed

I took a laptop on contract with Telkom about 2 months and 2 weeks ago, I had an issue with my modem this past Sunday& last night i sent an SMS to the technical support guys, they sent a few responses& thereafter they was no response& the issue was not resolved.Today after work i went into Telkom at Fourways Mall,the sales acknowledged that the issue was with my Modem, he then suggested to book it in, I then inquired with the manager on duty that I could not wait for a month I needed the modem to access work emails as well as my school work as am in the middle of my exams. I then asked how they could help me,they suggested that i Personally go purchase a modem at CNA or Game, I was also rudley told by the sales that he was not IT and he also suggested that i dropped my modem in the water so i could come claim a new one. I got a rude awakening as i was embarrassed in front of the staff as well the customers present instore, the manager never intervened when i was personally attacked by the sales. The sales consultants got aggravated and got very personal with me.I was appalled with the treatment of consumers at Telkom and poor management as well as the inconvenience. Am disgusted
