Mweb not assisting

I app**** for a fiber line to be installed in my premises. it was activated last month and the first debit order mweb was collected and I asked the bank to return it as my system isn't working at all. Every time I call they give me a ticket number and say that if the fault isn't sorted out with in 48 hours I must call again. Its now 2 months later and I still do not have any wifi at my premises as yet. And Mweb is sending me a invoice for 2 months payment. I have been asking Mweb to please send a technician over so that they can come and look at my system and they haven't sent anyone as yet. I contacted the Vumatel technician who ended up giving me a snotty reply that I must get Mweb to sort out the problem as the object number of the unit that's fitted in my house, and the object number that's on the Mweb system isn't the same. I am not sure if Mweb will read this but I would like to ask them if they do that they please contact me so that I can get this sorted out.
