Terrible service, no techician assistance and suspending account with out crediting the problem, and keeping my deposit

I have a 4mb line and a landline. I have had hardly any internet access for 3 months. ever since another company laid fibre in our area, and no use of my land line since lightening damage 6 weeks ago. I have logged numerous complaints and no one has fixed the problem. Now they suspend my account for not paying as I will not pay for a service I do not have.I have also never had use of my allocated email address so I cannot even login to check anything. I had to pay a R700 deposit that no one can locate either
