Pathetic service, Telkom is only after your money

I am on 5GB Wi-fi contract with Telkom since last year. For all the months i have been with Telkom I used to not finish my 5GB in one month and I would download games for my kids it will not deplete. Since last month my 5GB for the day and 5GB night depletes within a week by only using Google. I went to the store no one could assist. I tried calling customer service I hold for 30 minutes until my airtime finished no one picked up. This morning someone from Telkom called they say that they noticed my data depletes fast so they offering me more data for less, meaning I must pay more money. When I told her about my problem that is strange but could not assist with anything. I am monitoring my consumption and to type this complaint only it took 500MB. This is very sad and no one to run to as Telkom is not willing to assist and they know that I cannot cancel the contract as they will charge me cancellation fee that is why they dont bother, they just know at the end of the month they will get their money. This is my first media step to complain i am looking for another platform where the message to everyone to play far away from telkom is spread very fast. I regret the day I took my contract with Telkom, This is the first and the last and will make sure that no one that is close to me touches Telkom. Very sad as I write I cannot stop crying as this affects my small business i cannot read the emails when the data depletes and I cannot afford to top up when the data depletes as my business is still in startup phase so no extra income yet. i really regret being Telkom client.
