Dstv Signal doctor beware

Beware when using the company Dstv Signal Doctor they are rip offs. They charge you R475 for 1 dstv connector. They told me it R350 for a call out then charge R400. They told me that my labour would take 30 minutes at the cost of R400 per hour then they charged me R850 for 45 minutes. They make promises that they will come at a certain time and do not. Please be aware of this company.
