***** on my WIFI contract>>>>

I have a contract with you guys since March/April - it has just been down hill for since then>>First i had problems where my WIFI was not connecting at all and i had to buy 1GB for myself which cost me R160.00 for MTN - and that you guys need to refund me for as i pay monthly for something that didn't work and was inconvenienced. I was transferred from pillar to post then and eventually i had to buy a new sim card - swim swop - which i paid extra +-R120.00 another cost to me - this was in October - so you sold me a faulty WIFI and then a sim>>>double cost to me>>>>

now my second saga again with you guys - where i am told go to the store - then from store call the number - why have a call centre when your service agents cant assist - close down the call centre and pay your guys more at the stores>>>

there was ***** on my account reference number: ********** 591 - i haven't heard a word - my bill came out to +-R28000.00 for a capped router contract for R239.00 - explain that?there debit order went off the first time and returned and i got charged a unpaid item on my account! There 2nd stop order went through again as you tried again - and guess what i got charged again>>>I need all my issues resolved you need to credit me for all my time and inconvenience if not please cancel my contract as i really cant do this anymore - why must i call you on feedback and be sent from pillar to post for it>>go to the store - now call here>>>really. i need a letter on what happened for my bank to remove that unpaid and to take it off my payment profile - as this will affect by credit profile.

i want someone senior exec to contact me>>>
