Weak signal suddenly

<p>i am a current telkom user and had issues from of the first i took out my contract they gave me wrong deals and i had to pay cancelation deals with theyre mistakes where i had to reverse the fees and pay a penalty after that ive been inccorectly charged and also spending limit raised without my permission,my phone have been switched of for 2 weeks and they never bothered to manual activate it again now suddenly my signal droped at where im residing and it was always fine im getting full 3G signal but downloading speed is 1 mb and upload under 1 mb and my ping between 60 to 600 on the speed test and also my ping jumps around i phoned and they told me its the roof and to say i dont have any issues with the other service providers and also ass well it were okay for a year if this is not fixed then i will stop paying telkom and will not recomment anyone in the future to this ISP since i had this contract i had issues and poor customer care was given so please sort this out issues regarding my signal otherwise telkom will not just lose 1 client but more and i will discontinue paying my contract fees and block the debit order</p>
