CELL C - BAD SERVICE !!!!!

I called Cell C on the 1st of the month to ask why they had not debited my account even though there was more than enough funds available. They apologised and said they were having issues with debit orders but would re submit it. 3 days later I called again to ask why they had still not debited my account? Again they apologised and re submitted!! 2 days later I called AGAIN to ask why fund still not debited and they requested a do an EFT which I did and emailed to them. 1 week later someone calls me to say i am in arrears!! Obviously I was very annoyed and explained i had done an EFT at their request. They told me they would look for proof of payment and allocate. 5 days later i called to confirm as was assured the account was sorted. Today the debited my account TWICE by R1028.00 x 2!!!! When I called they told me they do not have my ETF or proof of payment even though i have emailed it along with all my details to ALL Cell C email address, support, proof of payments and customer services. I used to always recommend Cell C to anyone looking for Fibre, on Facebook to my friends and clients but now i will be warning all to STAY AWAY!!! As no one at Cell C can assist me with the extra R1028 they STOLE out my account !!! Very Annoyed !!!
