A double glazing salesman has been warned not to contact a Bristol customer after claimed he was inundated with unwanted phone calls.

Wayne Donnelly said a sales agent from Safestyle repeatedly called him when he did not accept his quote for new windows and doors for his Shirehampton home.

After complaints the salesman in his 30s has now been given a harassment warning notice by police and had his agreement with Safestyle withdrawn.

At its worse Mr Donnelly said he received 33 calls in one day from the agent who he felt was trying to “bully” him into buying products.

The 35-year-old said he first met the salesman in January when he came round with a quote.

“He didn’t have a good attitude and he seemed to challenge me every time I asked a question,” the locksmith said.

“He gave me a quote of around £8,500 while we were chatting and I eventually got him down to £3,600, but then he just got the contract out.

“I said I still was not sure about the price and whether I could afford. He did not take it well, so I eventually asked him to leave and complained to the company.

“From then on I started to get more and more unknown phone calls where someone was just hanging up.”

Mr Donnelly said by mid-February some of the calls included threats about ‘ruining his businesses’ and he contacted provider Vodafone in a bid to get the caller blocked.

The phone company gave him the caller’s number to block and Mr Donnelly decided to speak with his ‘unknown’ to him.

“It suddenly just dawned on me who I was speaking to. I asked him if he worked for Safestyle and he said yes. I told him I was going to the police,” Mr Donnelly said.

“To me it feels like they try to bully people into getting new windows and they cannot allow their staff to treat people like that.”

A spokesman for Avon and Somerset Police confirmed they were investigating Mr Donnelly’s allegations and said a harassment warning had been given to a suspect from Birmingham.

He said: “A harassment warning informs the suspect that an allegation has been made against them.

“It explains what harassment is and give advice about how to avoid it. The suspect signs this but this is in no way an admission of guilt.”

Safestyle said their canvassing agent had denied harassment.

However a spokesman said the company had apologised to Mr Donnelly, sent flowers to his partner and were in the process of pricing products at a reduced rate for him.

“The behaviour of the sales agent, as highlighted by Mr Donnelly, was entirely unacceptable and inappropriate and is not tolerated by Safestyle UK. As a result his agency agreement has been terminated,” a spokesman said.
