Poor customer service

I received an email increase in my policy for extended warranty. I requested a call back. Received a call from Lindosipho Qaqawe who promptly send me a lower quote. I said call me back on the monday when i will decide which quote i will take.30june. No call on monday sent email. Another lady returned my call I asked her to ask lindo to call me cause he knows . No call from him. Serveral emails to him to call me no response. Then come 1st august anx the new amount is charged Again sent a request for a call back. Lady called. I asked what was the reason for such big increase. Reply was it can be anywhere between 7 to 22 percent depending on inflation. Again requested her to ask Lindo to call me. No response. I then sent an email requesting immediate termination of the policy. Then get a call from lindo. To confirm cancellation. I asked for a directors name. Not allowed to give. I asked for a managers name ..cannot divuldge this . He then said he did not have the time to call me. And any other person would have been able to assist me I requested his supervisor to call me. She did call back apologized but cannot do anything more. Basically not concerned they lost the business. Pathetic service
