TOTAL DISREGARD OF EXISTING CLIENTS

I had my sim card replaced after many days of frustration due to no response of emails. I have tried to query telephonically why my sim is not working but because I am visually impaired and cannot read a small number on the sim card they just cut me off. Never in the seventy three years of my existence have I come across such an *********** service provider that shows such a complete disregard for their clients. <br> May they enjoy all the success they deserve!
