POOR INTERNET SIGNAL

2 weeks ago my fianc? called Vodacom Call Centre regarding poor internet signal in Queenstown in Eastern Cape - After numerous frustrating calls it took Vodacom 4 days sort out. The signal came right but on Friday 5 June the signal again went down. This was reported to Vodacom immediately and he was advised that it would be sorted out. I also reported the matter on Friday night. I again reported it on Saturday morning. A lady called me back and advised that they are looking into the matter and a reference number was sent to me. On Sunday I again reported the matter. I was advised a technician is looking into it. When my fiance called on Sunday he was advised technicians don't work on Sundays but yet still transferred him to the technicians extension? I was called on Monday 8 June and informed the technician says there is no fault in Queenstown. Why then am I not able to go into the internet? My bbm messages are delayed as well as my whatsapp messages. Surely there is a problem. Last night when I reported it I was advised that I had never reported the problem but I was given a ref no- What is going on? I pay my bis but cannot use it???? Will they refund my bis to me???
