Poor Service

I contacted Mweb wanting sign up for the offer which they had advertised on their website for a LTE-A promo for R549 for 110Gigs p/m inclusive of a free router. At the time the offer was available and I have proof of such. They then requested a sign an indemnity which I did to which I only received a response on Friday afternoon stating that the deal had expired. This of course made me livid. Why do advertise something when it has expired. I was not told it had expired when I signed up called through. When asking to speak to the manager Nazeera Mohammed, I was given the run around by Linda Kwaza who kept me holding for 35min, which even after I mentioned it, did not apologize or offer to call me back. Is this how treat your customers? Do managers not take calls from irate clients at your company? This is appalling from both an agent and manager level. I requested for Nazeera to call me back, she has yet to respond to my request. Abysmal Service Mweb!!!!! When should I expect a call?
