No response from Sales after service request. No interest in providing advertised services.

I contacted Mweb Sales last week to port my Telkom landline number to MWEB Talk. Call centre agent informed me that account manager will contact me. On Tuesday 26 September I logged an online query stating my requirement. Their response was to contact their Sales department which I didn't do because I knew what the outcome would be based on previous experience. On Wednesday 27 Sept I lodged a complaint on Mweb's Facebook page and was requested to send my contact details which I did. Up till now I haven't received any response from them. I have been a loyal customer for many years, but after this blatant disregard of customer service I have decided to get a different IP telephony service provider and will most probably also move my Internet service to a new provider who understand the concept of customer service. I am tired of being ignored by service providers. I will also spread my experience of their non-existing customer service and Sales department on social media.
