Unstable fibre connection as well as poor WiFi reception

From the start we have had unstable internet fibre connection as well as poor WiFi reception in our home via Vodacom here in Yzerfontein. I was originally phoned by Vodacom who at the time promised me a better serve via a fibre connection to my home. I used to be by Telkom via an ADSL line as well as a cable phone line. Vodacome promised a much faster stable line via Fibre as well as a Voip phone line keeping my excisting phone number. Frogfoot then installed the connection to my home early in December - 14th of December 2020. At the time my new router from Vodacom was not delivered yet. I only received the router much later. A delivery person handed a box to my husband and told him that it was the router from Vodacom. We then waited for either Vodacom or someone else to come and set it up as was promised to us when we ordered the fibre service to our home. Nobody came and I then contacted Vodacom who then told me that I should just plug it in, which I then did while he explained to me how to do it. We then had internet but from the start our internet was not stable. The signal comes and goes. If I talk on my cell phone via WiFi I can only hear every second or third word on a call even when I am seated right next to my router. Most of the time the calls just drop which is very annoying. The router`s internet light is flickering rapidly all the time. I have been in contact with Vodacom several times who then Logs a service request but a few days later sends me a mail stating that my internet is working and that my problem is resolved, which it is not. This has been ongoing and to get any proper service from Vodacom is impossible. Nobody at Vodacom understands my ongoing problem - I do have internet but the connectivity is poor and unstable. I got a private company out to try and see what the problem could be. Even my range of WiFi reception is very weak and I had to get Boosters to try and improve the range. This private person told me that it could either be the fibre connection to the home ( FTB or STB) which is not properly connected or the Vodacom Router which might be faulty or not of a good quality to extend the proper strong signal around my home. This I have explained to the Vodacom call centre time and time again, but without any luck. They have promised me that they will send a Technician out, but even that has not materialised. I just receive a mail stating that my internet connection is restored and the service call is then once again closed. The call centre has also told me to take my router to my nearest Vodacom shop to be checked. The nearest Vodacom Shop is 80km away. I cannot believe the struggle I have had to try and get a working Stable connection as I was promised when Vodacom contacted me at the end of November 2020 and promised me a better faster stable connection than what I had with my ADSL line. About a month ago I went to Malmesbury and visited the local Vodacom shop there for them to test the Router. They could not assist me. I have requested to cancel my service with Vodacom and was told yesterday that I am still liable to pay for the router as I have only been with them for 2.5 months and not yet a year. I will also be liable for the Fibre connection fee to my home. This is unacceptable as I have been struggling with their poor service from the start. I was never informed that I will be charged for the router as well as the connection if I cancel the service. I was only informed that I could cancel at any time as it is a Month-to month Contract. Another lie from Vodacom. Vodacom is only interested selling their phones and services but no follow-up nor customer care.
