Bad or No signal for to WIFI usage.

Our Internet signal was getting worse every month, the router was almost in every area of the house and no descent signal anywhere. We pay a lot for this service and we got fed-up and phone them to look at this problem. Their call center representative professional response to us where "There are to many client at Telkom, that is why you have bad signal" my husband was speechless, he then give her a nice gesture and said "then why do you have so many clients, cancel some of them", she responded with " She don't know" this is TELKOM for you!!!! So we are cancelling our subscription.
