Rude staff

Good morning 1life insurance I would like to express my concern about one of your sales consultants. I made an enquiry for funeral cover a few weeks ago with a gentleman who was informative and a great help and was gou g to take up the cover with him. Now since then I've been getting bombarded with calls day in and day out and I already set up a time and date with the gentleman when to call me but this other lady kept calling me incessantly. I'd cancel the call and literally 3 seconds later she's calling and I'd be getting up to 5/6 calls In span of 5 minutes continously. She's calling around working hours and yesterday in particular I was in a meeting and then training from 8am till 3 and I keep my phone in case of emergency. I had a tea break and answered one of the calls this woman made and I said please don't call me during working hours I'm at work I can't speak. I kept receiving these calls regardless hours later. Then Later around 5:25pm I received a call and I answered and this lady says to me in vernac verbatim "skang phaphela wena nxa" and before I could respond she hung up. Now as a reputable company wanting people to buy into your product/s I don't know how this can be allowed for your consultants to be allowed to call clients and say such. No restraint whatsoever and outright rude. How is this allowed!?? How is a person on the job allowed to call customers and say such. It's totally unacceptable. She couldve asked what's a, better time to call but this is rude. Please handle your staff. Please
