WORST SERVICE EVER RECEIVED!

I was unable to load my Blackberry internet service via cellphone banking. The consultant loaded BIS instead of BB10. This issue was supposed to be resolved in 48hrs but it has now been 8 days and absolutely no response from CellC. I have called every single day since the 3rd Feb 15' and my call is always been escalated & advised that they await a response from their backoffice! I am shocked at how so called Team leaders are being paid to do absolutely nothing @ CellC! They certainly do not pride themselves on service and I am so disappointed that after so many years of being a loyal customer that I am receiving pathethic service like this. Will this issue EVER be resolved? Will my BB10 be re-loaded as I have already lost a week of my 30 day service? Will anybody EVER call me to update me or is CellC to busy for even that?!<br> SAJITHA SINGH- ***<br> <br>
