Poor customer service - administration

I received a voucher in April.. I went for a treatment on the 12th August. The treatment was lovely and ladies were very nice.

When trying to pay. The voucher did not read. Apparently they needed to sort this from headoffice.

I left the voucher with them to be replaced. They assured me it would be sorted asap.

It is now the 27th August. Over 2 weeks later and I am still waiting.

I have been to the shop once Called once And emailed headoffice.

I still have not had any feedback.
