No wifi. No email. No service

I reached my cap on Tuesday 23 February 2016 and then paid for another 2 gigs, thinking that was the problem. Since then and after a couple of calls, we have still had no internet use in the area. And today, Sunday 28 February, I cannot receive mails and I cannot log onto my webmail account. What the heck is going on? and can Telkom just come out and sort it out? I know that Telkom has contracted a company to lay fibre lines in the area - has that affected the use. Any idea where to from here???
