Disatisfied Client

I wish to express my extrem disappointment and dissatisfaction with the said Service Provider. I have taken 2 contract with Telkom in September this year. I have been experincing problems with the network that keep droping. Messeges are received several hours later. When one trys to call me it goes straight to voicemail. i ahve been to the store on a few occasions and all i got is excuses. Now the phone comes up with a sim errror and am unable to use the phone at all. My cellphone is a esential to me as it appears on my business card and helps me pay my bails.
