No data service for 10 days

On 23 January 2016 I contacted Telkom regarding a bad voice and sms signal at our home. They made an appointment for 13h00 on 8 February 2016 which was not kept. During this time I made numerous calls to them regarding the complaint. I also started having issues with my data connection on both contracts and since last week Thursday we had no data connection at all. If we move the modems to another area about 1 km from our home we have full connection. We explained to them that the problem is area related. I kept receiving promises of call back, of escalation, of mail feed back yet nothing happens. This the worst service I've ever experienced with any supplier. My name is H A GREEFF. SERVICE CALL ***7
