TomTom Bad service

I am very disappointed with TomTom repair and return warranty process. I bought TomTom runner 2 in December 2016 . I started giving me problems beginning this year around February 2018. I have phoned TomTom and they promised to send the courier service to fetch for repairs, well that did not happen. Then I dicided to continue using the watch because I needed it for my training runs since I was preparing my Comrades marathon, I was scared that I might not get it on time. Well they did assure me that I will get it back within 10working days but I chose not to phone their courier service as they instructed, I dicided that I will phone TomTom after June which I did and finally they sent the courier to fetch it on the 30 July 2018. Today it's 9th November 2018. I must say I am really disappointed with their services, I have been communicating with them but they send me back and forth.
