Lost signal - problem ignored.

We have been having trouble with the Vodacom signal since 21 June 2018. When we phoned Vodacom we spoke to Alexander and he said that it was just congestion due the Happy Friday promotion. The problem persisted and after complaining again when we were not able to hand in the VAT they said they would look into the matter. They sent Vincent on the 5th of July to take a look at the matter. Vincent helped us look for the best position to place the routers so that we could at least connect to Vodacom. This helped so that we could at least work even if it was a very slow and unstable connection. At that point we would lose connection every 10 minutes or so and therefore we would always have to go reset the routers if we needed to send an email or work on SARS. A 328KB file took 1 hour and 8 minutes to upload. Vincent had promised that he would get back to us once he had taken a look at the towers that service the area. The following week we did note that the internet was working faster, but we still could not stay connected. When we tried to make contact with Vincent again he was on Family Responsibility Leave and we waited for him to return to work. Once he returned to work he did phone us and promised that he would come and take a look, but he never came. We have since sent numerous emails, but it is clear that we are being ignored as he does not even bother to phone back. It has now been more that two months that the internet has not worked properly. Last week Friday we would send emails and then it would show that it was sent but the emails were never delivered, when we filed returns on SARS it would show that the return had been rendered, but the return was not rendered. We were just lucky that we noticed the problem otherwise we would have gotten large penalties from SARS. We still have to reset the routers throughout the day and programs that are reliant on the internet are most of the times not working. I have had to at times take my laptop and portable router and ride with my s****** and stop on the side of the Percy Fyfe road and do the SARS filing at night because we are not able to connect properly during the day. This is not very save and not fair as we pay for a service every month. We have been customers with Vodacom for years and this problem only started on 21 July 2018, surely someone must be able to fix this.
